Where he talks about tank 25:20 in video -  Video link:  
http://gamerescape.com/2013/09/20/tg...h-translation/
Listened  to it again, but I don't hear anything about introducing new  levels,  he says it's already strong right now, players just haven't  researched  it enough.
Unless I'm deaf or there is a section missing in the video... w
Can anyone else confirm?
EDIT:  Listened to that specific section over and over and I still don't  see  how the other person got "Wait until we introduce new levels", if   that's the case he would of said please wait for an update or patch 2.1   for Warrior buff. No where does he mention that, he says Warriors are   hard to play, you'll need additionals (most likely meaning additional   cross class skills from Puglist and Gladiator) and that the players   haven't researched enough, dev team uses Warriors as they are really   strong, and they recommend warrior."
