i think that you used to play as a poko ! and you should know that poko can bee tank as well ! if proprely geared , same for buffer so groupe would bee karma poko dende buffer plasma ! if u take a tank it's to do it the save way
difference is that poko is a tank which deals damage and gives speedbuff every 20 seconds. buffer buffs at the beginning and can go afk.
I also play an ultima and am against those changes.
