First impression for decimation of addons in Midnight from a healer's perspective

Perhaps they should consider adding ability timelines for some non-boss enemies.

Or the game could just tell you who has a hit incoming without getting addons involved. That would be better.

We could be pessimistic and assume Blizzard would fail to settle into their new position well by leaving you with a mechanic like that anyway, but I think that’s premature. and when it happens they usually do something.
