Yes the funny thing is if Ubisoft gave us more Loadout slots we would buy more stuff there is so much great content to buy but if it's not convenient to equip and use it all why bother spending the steel?
Ubisoft I propose you create a reward system maybe every 10 or 20 reputation levels you get an additional Loadout slot for that hero. This encourages leveling up of Heroes and encourages buy more content seems like a win-win to me what do you think?
