You mean gear heavy, the mage tower required a certain amount of gear to even stand a possible chance, it wasn't just a purely skill. 8.2 has stuff for non raiders, it just depends on your perspective. I wouldn't call WQ watered down, they're no more hard then the standard quests. Honestly I enjoy myself, I just know I will run out of Wqs to do.
And no one shotting isn't some great mechanic to quests(Especially if its one of those fast casting spells)
