Sooo yeh, Mercs can level up and gain atack, HP per level, or w/e (ofc stats of a lv 1 Merc < current store one) possibly the Merc can only level up in BvB. something random Ross was thinking of when he was reading Irinub's post, only problem(s) is BvB farmers, and all the *****ing about "OP" Mercs making it unfair for those with a lv 1, but though luck that is what levels are for.
