Yeah kwon is a dirty backstab hero does it many times in this video (using backstab without landing a stagger first) a stagger is a ministun-like animation lock mechanic. It stops the other warriors/lancers from blocking. In this video auto warrior's auto attack (first hit) is a stagger which can be reset by block so it was pretty imba.

A year later they would remove that and put stagger on one of their other skills (rising fury) also buffed the damage of warriors skills by making scythe (that spinning skill) fast chain with some skills.

What I liked about tera pvp the most was that it was all about control. Part of the reason I got banned was because I would call out top tier PVE players to fight me in lvl 60 gear (gear from the time this video was taken) and id DEMOLISH them most of the time without ever getting touched. Id **** all over their weak excuses and apparently thats being "toxic" kkkkkkkkk git gud. I think you would have liked the gunner class cuz I know you like big damage and gunners are just massive AOE damage.
