I'm constantly doing kt4 runs to reach lv56 so that I can focus on endgame content, and as I do the runs, I'm unsure if I should switch between all my pets to level them up a bit, use whatever I want, or keep using the best one(s)? I'm a lv48 warrior, and the two pets that I have and prefer are Courage (lv42) and Ironbite (lv40). I also like Tankton (lv36) for the shell ability, Cerella (lv33) for the free +60 armor, and Flounder (lv30) for the dodge ability. All my other pets are only rare and are lv20. So I don't know if I should only switch between courage and ironbite, or use whatever I feel like using. I dont want my runs to be a waste of xp for my pets, if you know what I mean. I figure that I'm bound to find better ones later on, so does this really matter?
