what i know:
1. if you run even m+2 you receice 845 items, if you run m+10 you also receive 845 items with same chance of proc WF or TF...
2. number of chests 1-3 depens on speed. so if you there for items it's better to clear m+2 with 3 chests then m+10 with 1 chest...
3. person with key receive new random key if dungeon done in time and lost key if failed.
what i want to know:
1. weekly chest reward. this week everybody receive 845 items + new keys. don't know if it's intended change or not. all previous chest revards depended on best level clear and formula was like 840+lvl*5. so if you clear m+5 then you receive 865 item... but last week it changes and i want to know how new system works because if ilvl of item doesn't raise then i lost the last reason to clear high lvls of mythic dungeons...
2. how exactly you receive new keys except weekly chest? i don't see any single key drop from last 20+ m+ runs. 2 weeks ago i have seen smth like 1 key drop every run to random party member.
3. and the main question is - why i want to clear higher lvls of mythic dungeon if i receive exactly nothing from it compared to m+2?
