what ilvl should you have for reg mythics and +2 ...i have a key for DHT+2 but my ilvl is only 847

Plenty of groups boosting
Use the dungeon finder

what does "groups boosting" mean exactly?

sorry for retarded post but literally no idea, you get a key and people run you through it for free? or?

they leech your key for AP and legendary chances, so you go there trololo and they do all the job, bt that happen usually only on mos, cos and nelth

At 847 you will be fine in a +2, especially DHT because its a easy one.

I'd say 835-840 for regular mythics

845+ and you can do Mythic +2 or +3 but it may be difficult finding groups unless its your key.

Going beyond it will determine what the week is as to what ilvl you will need to be successful (what the trait is, teeming, necrotic, etc)

He will never have to worry about Necrotic, it's only 7-9.

I do key carries all the time, shoot me a PM sometime if you're US-ALLIANCE
