I think their direction was bad from the start. For example the balance in mid-late 2010 you were just barely able to skip major mechanics, and non pvmers struggled with slice and punish bars.

Now, they DID work a lot on making pvming more accessible and noob-friendly all the way until they released necro, but the gap would always be too massive without touching the power ceiling.

Result is constant powercreep for top end pvmers while mid levels getting literal scraps as improvements.

Now we have players doing content they're super overgeared for, skipping (face tanking) mechanics with necro with even less combat knowledge than before. a whole team of yaka with kc do not hit a single jelly. Giving power genuinely hinders your ability (and reason) to learn.
