I like the revive change. I think it makes it easier to play arbitrations with friends. Previously if someone died, then bang they get to sit out while everyone else has fun. I think that's counter to the spirit of the game and I think DE made a good call changing it.

I also like increased scaling. I did a few arbitrations early and was pretty disgusted with how little focus I got from them. If they gave me as much focus as ESO I'd play them a LOT more.

I do very much dislike the ~10 minute reward scheduling. I feel that half a reward every 5 minutes would be better, but whatever. It's a pretty fun mode and I still do them every now and then when I can have fun with a 300% Khora or something =)
