Yeah, it's incredible hard, since they all have different growth rates. It's just frustrating knowing that Auto Battle will be locked to a lower damage, front row skill when for a little over 10 more MP I could be using a full-screen AOE attack. It wouldn't be bad if, when all skills are mastered, you could pick which one to use as your Full Power/Auto Battle special, but you can't. The game locks in whatever skill hits 10 first, regardless of which slot it's in, so generally it's the weaker I-rank spells that manage it. Reaching 10 in the other, more damaging spells afterwards doesn't change this, since the game supposedly "remembers" whatever was first, so even when I manage 10 on Prophet All afterwards, the game will continue to use Prophet Forward.
That's what I'm thinking of doing, haha. For the 4*, I don't really care, but I want the best possible setup for 5*, both for personal use as well as those on my Friend List so they can get the most out of my Auto Battle. I think I'll wait until I get close to Level 10 for Prophet All (without letting Prophet Forward, my third skill, hit 10 first) and then keep my first/second skill (thankfully, the heal back row skill isn't classified as damage so it won't affect not using Prophet All) and then re-roll my third. I don't really need it anyway, since I can't see myself ever wanting to attack just a single row when I can attack everything for 10MP more, it just doesn't seem worth it. While I would have liked to keep both, I'd rather lock Prophet All as my Full Power/Auto Battle Skill than Prophet Forward. I just wish it was easier. Who knows? Maybe I'll get a really nice single attack/low MP skill as my Awakened one, or maybe a team buff ability.
Heh, great minds think alike.
