2 changes to TWW Mythic that I'd think would greatly improve the minigame
@WarcraftDevs
1. Remove the majority of abilities from mobs. There's no need for a mob to have 3 different casts. Make it have 1 powerful cast like back in the day, you either stop it or take heavy damage. It's near impossible keeping track of everything happening currently, I'll attach a GIF of MoS bigpull back in the day where mobs had 1 frontal, 1 cast or a debuff. People want to do damage without dealing with 10 different mechanics.
2. Removal or addition of "Buff Scrolls" to raid buffs. (See War/DH/Monk etc). It's near impossible for a DK/Pala to ever compete with a DH in terms of damage output due to buffing the DPSers by 5% magic damage. You added engineering CR which nerfs the CR classes even more, so why not remove/add scrolls to make these classes a bit more competitive. We have seen these scrolls being added in MoP Remix so I don't see why the same couldn't be applied for retail.
Sure you don't have to play "meta", but unless you got friends willing to play with X spec you'll end up sitting in queue forever.
