IW is basically just a trophy, she’s not useful until she’s level 200+, i’d pump iso into OBW cause even with true healing she’s still indispensable cause of her AP stealing. If you need roster space for CMags i’d sell IM35 cause Thor is already maxed so there’s no need for a 1* tank on your team. Daredevil is probably the worst 3 star there is, so don’t pump iso into him anymore(keep him though in case of PVE/PVP required character or buffs.
Keep collecting Ares until you are ready to transfer to 3*. He’s better than Thor for killing big brutes. It’ll be some time before you can collect some covers and max him out though.
