During WotLK I used to think PvP was all about skill, when it was mostly about comp and access to PvE gear.
Which is funny because, fast forward to WoD, I remember the marketing for it went along the lines of "Engage in epic PvP battles where skill is the deciding factor more than ever!". When in reality the victor in RBGs was decided by how many boomkins or warlocks with PvE trinkets were on your team.
Good times regardless, but that e-sports marketing can take a walk.
