I think that mastery tasks should be updated to be on par with the game’s current state.
The fact that we receive banner tokens and gold, which offer little to no progression should be an immediate change. I propose that cards like the Wizard and the Mortar, who have a third set of mastery tasks, should have evolution shards as the reward for finishing mastery tasks. (This only applies to the ones unlocked at level 14.)
This way, we have more players logging in to actually play more, now that masteries have more incentive to them. New tasks should also be given out as well, it’s been a while.
