Occasionally mage and warlock, but that really doesn’t change the entire basis of the complaint. The OP has been pushing into higher keys, stricter prevention/add control has always increased in priority as keys go up, and has no direct correlation to fun.
Both casters and melee are doing plenty of things in regards to mechanics, going up in key level requires that but doesn’t mean there isn’t plenty of time to hit your dps buttons and “blast”. It’s just one of a dozen complaints aimed at neutering difficulty because people aren’t as used to higher keys. And the fact they’re harping on a specific thing such as “you don’t dispel” wah wah wah is evidence of a lack of understanding or playing other specs.
Either way, as long as I know my class and or the spec im playing, there is always time to hit dps buttons, players wouldnt be pushing above 10s otherwise.
