In C5 they nerfed leveling lower charaters with your pets , but now in C5 you can leave your pet to leech while you get exp somewhere else. Just tell party keep an eye on your pet, then run go exp alone. They’ll never know. Make sure pet has food, and if you summons pet youll have to come back to resummons every so often. Keep this on the down low. Also this would really speed up lving on a strider.
