Since this could be seen as remotely related to what we do over here:

Judging by the levels of activity in the Hearthstone section I suppose this won't catch anyone's attention, but for me personally this looks just like a desperation move.

Haven't played the game in a while, found the removal of the classic mode super stupid and frankly don't really care, just found it interesting how Blizzard actively chose to not even mention StarCraft in recent years' BlizzCons, but just NOW they introduce a crossover they should've done 8 years ago, when both games where actually healthy.
