As for Pyro and Air, I'm not sure. They boost damage from wands, staffs, and surfaces, right? Does INT also boost these damages by the same amount? I mean, at least one advantage of these two schools over Hydro is they have potential surface damage; Hydro doesn't. So one reason to invest in these schools is to boost the surface damage. unless you're saying INT does boost surface damage by the same amount.
I don't understand, did you mean the Pyro and Air already boost the surface damage?
Aren't those fixed value based on levels?
