I have been playing this game ever since it first opened. i love the potential it has, and how you kept on adding new crusaders with alot of new formations to use, however, right now the game has more than 70-80 crusaders, and 80% of them are useless.... so i came up with the idea of making Tier 2 crusaders, like buffed up Sarah or Jim or whoever, so here is how it works and i kept it that you will still make money out of event chests.

So the event will unlock x2 tier 2 crusaders (you guys would pick ofcourse.) upon unlocking them, your tier 1 crusader upgrades to tier 2 (it will keep its old gears and you can still obtain for it its gears) however, it will open up 3 new gear slots, and these gears can be gotten from the event chests/crafting(if you are planning to make that) the gear slots can either enhance some of its skills or maybe become an additional upgrade to a gear buff. The tier 2 Crusader ofcourse will still have its own skills, but stronger, or if you want to introduce new abilities for them thats up to you.

Ofcourse, this is just a suggestion, feel free change it however you want, or ofcourse just ignore it like the rest of the suggestions :)
