One thing i find REALLY annoying is the display of teammembers HP:
I.E when you get out of range and come back to your team they all show with their UNBUFFED hp. Now take a NT/MP/ENF/DOC or whatever with full HPbuffs(docbuff,essence etc.) they looks almost dead before you target the player. This is so g.d annoying and sometimes makes it hard to know who to heal in a group or even when to heal!!
Your whole team looks half dead if you get out of range and back.. until you target them that is.. VERY ANNOYING
