haha yeah that could be in awesome thing.

so in Recruit the combat system will be like in revelations and brotherhood and you will climb fast, and the guards will be less suspicious.

Assassin would again be like revelations, but it's harder to start killing spree, and you climb a bit slower.

Master Assassin would be like in AC 2 and climb like in AC2.

Mentor would be like AC1, both in combat system and in climbing and the guards would be a lot more suspicious

or maybe in Mentor there should stamina? but that would maybe ruin the game, i don't know. Anyway they're not gonna put it in the game, but it sure could be cool.
