Once you've beaten every campaign on every tier,
collected a ton of idols and can beat the hardest campaign,
maxed out talents,
unlocked all the crusaders possible,
unlocked every achievement,

Where do you go from there? even before you get to this point, doesn't the gameplay get too repetitive and vain?
Once you've hit this point in the game trying to collect any missing epics (if you are even missing any!) is pretty much vain.

I think Crusaders needs to add to the game play and move away from being an idle game a LITTLE. Off the top of my head, one way to help destroy the mind-numbing repetitivity of this game would be to create playable missions we can run our crusaders thru instead of the idle type missions we have now which we just start and wait for the timer.

Thoughts please.

Am with Teschio, here. Am very fine with the basic principle of the game being an idle game. And I also think, there's still a lot of stuff for the players to do before 'end game goals' becomes a threat for boredom.
