I love AO.
I do not disagree that there are underpopulated areas.
Here are some side things I would like to see:
More emotes,
Including /LayDown /Breakdance /combHair /thinking /onphonecall(which also sets you to AFK)
Benches outside Tir FT - have you seen how many people sit on the ground? - and why can they fix the sitting on chairs - i dont sit crosslegged on normal chairs.
More field interaction, mirrors, taps that work, radios.
More Music - after a few hours I have turned it off. or CD controls in the game itself - we all play CD's, perhaps with fancy skins that do all the EQing in you "implant of CD control"
The ability to play soccer.
Drunkenness.
more temples.
Amen.
