They probably will increase the cost to weaken Druid and Rogue.
Is it about the Warrior with dragons that punish opponents for playing minions and what exciting can be found here while Priest who did the same was not exciting?
DK and Warrior (without dragons) are already strong, only one of Warlock’s cards will be touched and probably Warlock will remain strong too, so I am preparing for one hour games (actually, for moving to BG).
But my expectations are mostly a story of relatively high ranks. Some trash that can be countered, but requires thinking to counter it is probably coming to low ranks in 3… 2… 1…
