DDO doesn't have to balance anything, of course. I wouldn't be running with a melee Elf Paladin/Sorc if I needed Turbine to min/max my builds for me. But there
is a difference between fun and balance. You can have fun rolling a Drow, but its a pretty obvious fact that the primary role for Drow is currently for easy 32-point builds.
Almost every race has at least one niche laid out by Turbine, areas where they shine. An Elf is crucial for a scimitar FvS or a Kensai Arcane Archer; a Warforged is crucial for many Arcane melees and Greatsword FvSes; a Dwarf uniquely apt for an AC/tactics tank; a halfling a sneak attack virtuoso or Dragonmark saint. The race left out is Drow. Drow's major selling point is their cheap stat buys in an inferior stat arrangement at 400 Favor. That's not a "fun" issue or a "min/max" issue, but simply a design issue.
I understand people who say "Drow are supposed to be meh; its the Favor system." but I don't get people who say "Drow are balanced as is."
The value of a race is not summed up by how many points it gives. Warforged are a great example -- they are crucial races for many builds, including self-healing arcanes and adding melee oomph to many THF builds (bards, FvS, &c.). From Korthos to Epic.
Conversely, no build (besides the questionable 20Dex/18Int mechanic rogue) needs a high DEX, CHA, and INT, and SR 11, and rapier/short sword enhancements. +2 +2 +2 here do not equal +6 in Balance-land.
Other races provide what Drow provide better, in some cases at higher resource cost.
-- By endgame, humans generally have equal spell DC's, higher UMD (human versatility), +50-70 HPs, and/or better DPS from Kopesh.
-- Elves have better weapon selection (bows/AA, falchions, scimitars, and rapiers) and true 32 point buy, and Dragonmarks.
-- Halfling assassins achieve higher sneak attack damage, AC advantages, etc.
Since most classes want a high CON, the "bonus" INT is a wash. A halfling with 14 CON and 16 INT = the same amount of points as a Drow with 14 CON and 16 INT.
Since Drow lack enhancement options to boost CHA and INT, the Drow's advantage in those stats is minimal -- only +1 ahead of the human. The other points are mostly wasted. Again, three +2's are not the same as one +4, and 4 extra build points.
Balance isn't the end-all be-all of DDO, and I'm fine if Drow stay meh. Just like I'll be fine if clerics stay meh. But they
are meh, and saying that they are fine doesn't make them less meh.
