AI that doesn't do the Benny Hill run around
AI mobs that act like the races they are modeled for rather than all mobs acting like poorly coded PvP bots.
Mobs with unique abilities set for their races rather than a player based class: Example - spiders are always poisonous and should not need to use Apply Poison.
Real dungeons with the "feeling" of a dark, dank and closing in on you type of "feel".
Dangeous foes that are really dangerous vs the scrambling idiot AI trying to be a grief runner: A foe that when engaged gives the players cause to be wary. Add some knock backs to the "big ones" and knock downs to normal swings. Add in some "auras" that make for a high pressure situation, slowing attacks, degen, vamp auras, ect.
Repeatable instanced quests with randomized mobs or mob builds; or better, randomized areas (overland and dungeon) that are theme based with randomized mobs or mob builds.
Unique non-tradable earnable armor and weapons based off of the Repeatable instanced quests. Make there be a reason for everyone to want to do them, vs just yet another cookie cutter farming build area.
No elitist areas, but add plenty of end game areas. So far the "Elite" areas are nothing more than cookie cutter areas of interest. /yawn
Remove favor so other end game areas can finally be quested in and enjoyed by all.
AND STOP FOR THE LOVE OF ALL THAT IS GOOD! STOP TRYING TO SHOVE PVP DOWN THE PVEeRS THROATS! If it's not a Factions based craptastic game mechanic, it's the freakin AI trying to act like a PvPer... a badly coded one at that. Stop. Enough already. Get a clue, not everyone likes the GW PvP game.
