So in light of the many discussions seeming to disapprove of high end raiding, what enhancements to end game play would make the game enjoyable? If you're pro mythic, what changes would you want to see?
Personally I like mythic as a difficulty, however I still believe the Ulduar model was best - where 'hard-mode' is activated through some encounter mechanic which inherently alters the fight difficulty. This approach might also sidestep some of the major re-tuning /design requirements of the fights themselves enabling resources in other areas. This also keeps things integrated into one instance and makes things more accessible. (Most guilds imo don't want to do multiple runs, or don't have the time and must dedicate to one difficulty or another per week.)
Also, the different gear models for mythic is odd. Why put in subjective 'incentives'. For the most part, my raiders hate the current tier sets. This in my opinion is the worst 'waste' of resources in this regard. Most raiders are content to raid, knowing gear gets replaced anyways, at the difficulty they're comfortable at. Perhaps a more realistic reward for hard-mode would be guaranteed war-forged?
One area I truly miss are additional dungeons which expand upon the story. Cata was the last expansion to offer additional dungeon content. For MoP's strengths the failure to introduce additional dungeons was a problem people overlook. As a result WoD will likely not see new dungeon content beyond the mythic mode refresh and time-walking, which is at least more than what MoP offered.
