I’m not saying there wasn’t powercreep in the Tank & Support roles. There might’ve been some, but after the barrier nerfs I saw and still see no reason for the ridiculous amount of nerfs that majority of the tanks have received and apparently I’m not alone in this, seeing how short the queue times are for tanks. Same goes for Support.
But, not saying there isn’t power-creep in DMG… The role with the most heroes, the role with the most players and the role with longest queue times, is either being purposefully ignorant or just dumb. 
In other words, I have a hard time believing it.
But again, like I said previously I’m not saying DPS don’t need buffs. Some heroes in the DPS role do. But at the same time, there are a decent chunk of DPS heroes that have no reason to do the amount of DMG they can do with the nerfed Tanks & Supports. It makes no sense.
