I really don't understand why there are so many negative cunts in this comment section. This is a highly competent player having fun by making PvP videos. His music is enjoyable, his editing skills are decent and his combos are great. What is there to be so damn salty about?
TERA isn't fucking Minesweeper, Tetris or WoW. Contrary to what a lot of people would think, it takes quite a lot of time and dedication to perfect reactions, combos, counter moves and trying to outsmart a proper good player with ANY class. Trying to master them all is like becoming the best biologist, mechanic, cook, phycicist, athlete, musician and politician at the same time. Just pick a class that appeals to you, dedicate yourself to it and have some bloody fun with the game.
