I like magic being grouped together, but I still liked the Anima triangle from FE10. It would actually give a reason for mages to use different elemental magic.
To be fair, the anima magic triangle wasn't
a reason to use different elemental magic. Your magic users tend not to take much, if any, damage from the others mages. You still have a very high chance to hit, and +1 damage doesn't mean much when your B rank (for example) Arcwind tome, is 3 might stronger than C rank Elthunder. (Meaning that even after weapon triangle differences, the Arcwind is doing 1 more damage.) Only real reason to touch other magic in FE10 was to fry up some beasts, zap some dragons, or blow some fliers away. Otherwise, you just use the strongest tome you had access to.
And it's true, they're pretty bad at balancing magic. In FE4 all elemental magic had the same might, but different weight, giving a massive advantage to the lighter type. FE5 was just weird, magic-wise. FE9 had Thunder magic being stronger than anything else, giving you little reason to touch the others. FE10 was usually a matter of using whatever your primary magic type was, because it was the only one you had a decent weapon level in.
Combining them into a single group eliminates the Weapon rank issues, but a weapon triangle would have been nice.
