Okay, are any of you vanilla WoW players? Unlike Valve creating unbalanced weapons, Blizzard constantly threw classes out of balance. Burning Crusades PvP was on the slower side, but was more strategic and highlighted raw skill. Following 3 expansions, they constantly screwed up balancing issues leading hardcore PvP (ie: tf2s comp community) away while only pros(+streamers) and new players continued. To fix 3 terrible expansions they had to roll back and re-scale all healthpools on players, raids, and NPCS to attempt a re-balance on terrible damage and burst reliance.
Did I mention Blizzard absolutely LOVES RNG? Our communities disdain for random crits, is a concept blizzard absolutely LOVES. Imagine the frustration of losing a match because the enemy was lucky enough to get the 15% stun chance 3 consecutive times in a row in a matter of <10 seconds, leaving you in a stunlock for up to 12 seconds. This is how a Blizzard game is structured, if you're looking for a skill-will-prevail type game, you're looking in the wrong direction.
