The removal of the classic and basic set, so that the standard meta does not revolve completely around the same cards. Either they make a sub-rotation of hose cards or just delete it from standard and make reprints in future expansion.
A restricted mode so I can play with old cards whithout encountering frigging busted decks at every turn.
Arena should feture one expansion at a time, including reprints or the sub-rotation of the classic and basic set previously mentioned.
Rewards for ranking that are actually useful.
And please, a rank system for Arena, please.
Actually, just copy MTG Arena. Done. You got me Back.

I've King Krush and you can do greaters combos with Kathrena Winterwisp.
Look this deck: http://www.hearthpwn.com/decks/999870-kathrena-winterwisps-hunter
Ofcourse, this is an example, you can do another better deck.
King Krush is NOT a dust, but its very complicated learn to use or build a deck to have a great use
