And view numbers in a thread are indicitave of what? If Ret paladins were buffed to the point of being competitive at glad level, you would see a huge thread similar, because ret paladins are extremely popular. This line of thinking is up there with using 2k ladder rep as the basis of the warriors are OP argument.
This is my best guess on what happened. Warriors were buffed, top end streamers and the like said they might be a little too strong, masses of those that follow either re-rolled or dusted off their warrior, average players (1600-1750 rating) were now losing to warriors who required no skill to kill in the previous season, said players ran to forums to QQ. Now you have this topic, where almost anyone complaining about them is just underskilled, period. No one here can nail down why they lose to warriors while also claiming they are playing their class at maximum potential
TL:dR for last part, get better.
