Right but why would we be discussing just base damage + magic scaling? Outside of the old legacy troops we've already discussed, virtually none of the newer troops, flat AOE or split, use just base damage plus magic scaling. Almost all of them scale with something else, be it troops, gems, whatever.
We can't ask for them to design in reverse. They've committed to the current power creep. The only way to make split damage troops relevant is to do like what they did with Tesla.
