OP’s suggestions are to make it more accessible to pugs, but they aren’t going to get past the first or second boss anyways most of the time so there’s no point in Blizzard putting in the effort.
Mythic is for organized groups.
But Blizzard absolutely SHOULD increase accessibility - and fun - for organized groups:
- Mythic should scale (like all the other difficulties) from 18 to 30 players. Maybe bump that down to 16 if 18 turns out to work okay.
- Per-boss skips are a must, or freeform layouts. Undermine’s actually pretty good here, best we’ve had in a long time.
(For perspective, I’ve run a CE guild for 11 years, now, so speak from experience.)
