We’re certainly open to the idea. And we’ve done real-time PvP before in Puzzle Quest, PQ2 and PQ Galactrix on PC and Console. Mobile is a different kettle of fish though, mainly due to disconnect/reconnect issues mid-game. I know Blizzard had trouble with that in Hearthstone.
We’re backed up with plans for the next couple of updates, but after that, it’s a definite possibility.
Quick note though - even if we DO add real-time PvP, there will ALWAYS be the current form of PvP (vs. AI) for everyone to play and enjoy - we won’t ever take that away.
