This is an edited cross post from discussion on expansion packs.  Look to one thread for the genral "discription and analysis" of and expasion pack and this thread to read the various played picks and preferences.  The post broke down into 2 points whn it came to how to spend your points, a comment on waiting for sales then my own personal reviews ranks from best to worst.  You notice in this discussion it is all about content but I FIRMLY believe buy content first and then play with races and classes later.  Yeah warforged are cool and half orcs can kick ass, buying content allows easy access to more favor points and thereby unlocking more content.  Really, buy adventure packs first.

First: Wait for a sale.  Just about everything goes on sale and if
you have something that looks really tempting and you getting near the
points to purchase it, start to fish the DDO stoe to see if it is on
sale.  Sales of 20% are the "common" sale and happen with all content abolut once a month.  However, every rare now and again a
50% sale occurs omn an item and this is pure awesome.    It sounds stupid but every
time you get you 25 points of favor from the mailbox seriously take a
look on what is for sale in the turbine store that day.  Heck, I pretty
much check it out every day because you just do not know when one of
theose 50% sales hit the system. It is how I got Delara's at 375 points
and was one of the best buys I've ever made. So, rule of thumb is this. 
Buy things only when they are on sale.  Jump on things if they are
mentioned in these reviews and have a 50% sale.

Second: I ask if all the vetrans could rank these picks in order of
suggestion to fellow furs who may be newer to game and just now deciding
on what to buy.  I really appreaciate the really hard and thourough
work Happenstance has put in here and I know we have been having these
discussions in parties online for awhile so please follow up on his lead
and add your "ranked choice" a little bit of why.

For me, it goes in the following order:

1: Delara's tomb.  Yeah it's pricey, but there is a reason for that. 
It is fun, challenging, has both a main chain and some neat stand alone
side quest, and the "voice of the master" really makes it feel like you
can advance quicker and more easily.   Getting groups to run this is
easy and even if you are a noob most people who run this are willing to
teach and the missions can easily be and should be played as a "follow
the leader" style since it is missing any obnoxious split party combat
puzzels (like xorian cypher). The XP here is awesome and fun to get. 
Really, if you can wait for a 50% sale and can get it, get it.

2: Three barrel cove.   I really like this area even if there are no
chains over 2 missions and therefore this area has no good end rewards. 
The open "adventure area" is one of the prettiest and most varied in
the game and the tropical feel really adds something for me.   Each
mission is really different and seems to try to make sure that each
party memeber has at least one dungeon to "shine".   Xp is ok but I find
it just does not feel that grindy because the dungeons are so varied.  I
think I just love to "relax" out in this area and bind the random party
together when nothing else seems to be running. Just remember to pack
your water breathing gear if you go it (guild has extra) as many
dungeons spend alot of time in the water.  Lastly I notice this has a
tendancy to a 50% sale day about once a month so if you got the 325
points to spend and your tired of waiting for delara's to go on sale, do
it.

3: Tangleroot.  Yes, the main adventure chain is a very linear
dungeon chain and the end rewards are only fair baring one major
exception: the blood stone.  This is a +50 Sp trinket so spellcasters
have every reason to run this area at about 4th-5th on normal to get
it.  I found this is absolutly money for favored souls, Sorcerrers, or
even combat rangers who really on constant use of barksin and rams
might. Also, the adventure area is REALLY pretty and groups are going
out here all the time.  If you want XP and find you are advancing too
slowly in the 5-6 range, this is XP heaven.  It is really easy to find
groups eliting this and the is more than once I've entered a group
running this elite at beggining 5 and came out mid 6 about 4 hours
later.  It goes on sale frequently and many guildies own this, a good
buy.

4: Necropolis 1: This is kinda my unsung anti-hero recomendation. It
is only 5 missions, has no adventure area, and the "chain" has this
nasty requirement of having to do all 4 subvaults before it allows you
to do the main vault and is therefore a serious a pain in the ass
somedays.  Also trying this without both a cleric and a rogue seems an
exercise in masochism. However, with all this said the XP and favor per
turbine poin spend is second to none.   It fits nicly in getting xp and
favor farming band at the level 5-6 range and, like tangleroot, is and
easy enter in at level 5-7 and come out level 6-8.  It also has a
tendancy to go on 50% ad about once a month. If you are the serious
farmer for Xp and favor this expasion is a really solid investment
return when it is on sale.

5:Catacombs:  Happenstance said it all; grindy as all get out with
only 1 or 2 end rewards even worth looking at.  The main reason to even
look at this area is it can be cheap and easy favorand xp and relativly
easy to solo most quests becuase it tends to be overleveled (all
adventures are considered level 3).  However, unless you are looking for
cheap content and just an area to practice your playing style and
control of your character, your points are better spent elsewhere.

6: Shan-to-Kor: My Least favoroite buy for several reasons.  1:
Adventure area is some small as to be laughable and is just more sewers,
which everyone is sick of by level 4 anyway.  2: The advetures are ok
but I find very unforgiving and not noob freindly.  Yes same could be
said for some of the other expansions posted above but I still find this
is one of the areas the suffers the most from bad and poorly organized
parties.  3: End battle is the untilmate of this as issue of not noob
freindly and is very diffacult. If party does not have plan they will
wipe.  And more so tyhan tangleroot it is hard to find a group that is
willing to run just to complete then end.  It is long, annoying and
really not worth the effort and not worth favor or end rewards.
