Just a couple of things I've noticed so far.

1: One of the weekly challenges is to sell 75 artifacts. If you run multi battle, you won't get credit for the artifacts that are sold during that time. That is very frustrating considering we now get 30 multis per day. That's potentially 30 artifacts.

2: Requiring us to beat 50 force/void etc champions per day is way too high. Insanely too high. If you have one of those champs per team it's still 50 arena battles. Nevermind the fact that you're probably going to lose a good amount of those thanks to the current meta.
