When I talk about keys being a joke. I mean reaching the highest ilvl weekly chest. M+ scales infinitely, so any way of talking about it wouldnt make sense.
For the record I think keys being a joke is a good thing.

Gear just doesnt make a big enough difference for bad players though. These people are playing a completely different game. They cant even do something that resembles their rotation.
Truth is, if these people do progress (more than 1-2 key levels), it will because they got good, not because they get the extra ilvl. Gear cant carry them.
