Yes.
i mean sure you’d have to actually switch the gear pieces, but if you want to carry a set of gear with you that buffs your character in a different way than another set? sure be my guest, keep that set in your inventory and switch it on the go if you so please.
guess what people do in world of warcraft if they play a tank or a healer class? that’s right, they keep 2 sets of gear with them so they can dps and/or heal/tank.
