I see them from time to time. To be honest, i find multiple Famines more annoying
First, thanks all for answering, it's true that with the recent adjustment , we won't see it soon.
Second… mana drain is no protection for a well build Devour team. You can fill a Giant Spider in 1 turn with the right banner, and 1 Spider will fill 1 or 2 Kerberos before you can drain them (it's what i use to farm Explo on Warlord).
As i said, me, i have teams that never even let the opponent play, so if i scout Devourers, i just play that.
But any game with a PVP system (fighting, cards, RPG, strategy), must provide fun, and a players has more fun when he can actually play. Even in a losing game, a players usually has more fun if he managed to play a little, cast spells, use cards and attack. Losing a troop in 1 cast means you never used it, and means less fun.
But hey, i've loved this game since Puzzle Quest 1 , so i'm no about to stop
