That's an interesting approach. Obviously your still HP starved so it makes some sense you are targeting HP rewards.I only leveled characters who mattered. As in meta ones I was going to be using regularly for PvE/PvP. Once you have those done, then my next target was ones who are feeders for 5* since I wanted the 5* cover at L280. Then after that, it doesn't matter much so sometimes I'd level for specific reasons (ie win a crash, that 4* was featured in PvE/PvP etc).Your 5* should not be leveled past your top 4*s. So if your top 4* are L280ish you should not level your 5* past that point regardless of covers. Even then, only level the meta 5*s and leave the rest unleveled.KGBP.S. Are you farming 2/3*? ISO always goes to farms because it returns so many rewards.
