I'm glad that they are paying attention to the Arena, and announced changes are welcomed, but this is very worrying:
Long term, we want build-around cards and synergy decks to be viable strategies, but we need an Arena environment designed to support that goal.
I will never get tired of repeating: the more synergies in the Arena, the worse it is for the Arena. This is the only mode where there are not so many synergies, it's one of its biggest benefits, and yet they try to feed us with synergies again. Can't we leave at least one mode where there are few synergies? Some players (crazy ones, I know) like to see yetis on board eating spider tanks, not a worsened version of constructed, like Duels.
