When grouped with others, i find the UI atrocious.
Why show only part of the persons name, you're screwed if you have two people with similar names, for example... Khaarnee and Khaarne.
How would you know which is which till mousing over them and selecting them?
Why only show the HP bar, why not the mana and stam bars too?
Why not have people shown on the map AT ALL TIMES, instead of it deciding it might as well plonk a dot on the map occasionally?
You should be able to do lot's of context actions by right clicking on people etc.
I don't understand that after 5 years of developing this game, you seem to have missed lots of really simple, important things... a game isn't just about graphics you know, functionality comes into play and is very important, we are, after all, supposed to be staring at the screen for countless hours!
Anyways, REVAMP the group UI (look at WoW for example... )
