Will KMS change the magic formula?

It's way too late for a major change to the magic damage formula. It would be nice to see the small int part get replaced by a quadratic luk component though, something like luk^2/2000*spell attack.

I think they just need to be REALLY careful when changing it, like trying to keep the numbers somewhat the same. It requires extensive testing, but I think it can work out. They just need to do a few things:

1) try a few different formulas. See which ones work without changing the magic stats already on items.
2)keep luk as a lower factor in damage since it's still a second stat, but make it have an effect.

Once they find a system that works, then can change the OP/UP skills by adjusting base attacks. If the ultimates do too much damage, they can reduce the base attack. If bossing skills still do too little, they can increase the base attack

Time consuming? Yes, they would probably have to test out the best one in beta for a while. Worth it? I think so. A decent amount of people that quit are magicians because they have nothing to do end game, and an improved formula could probably bring a good amount back.

Something else I'd like the see is a damage range for magic attack. The only problem with this is all magic skills have built in mastery. They really can't give a general range of magic attack since until you have all your skills maxed they have different ranges. This could be fixed with a 'spell mastery,' but there's not really any room for it. I think mages are just gunna have to deal with sum of their MA.
