Some clarification questions:
Block the Sun vs. Static Charge: In the current PvP meta, animate weapons are shoulders above ball lightning in usefulness. Why then is BtS a T1 ability whereas SC is T2? I can understand if you want to keep it accessible, but then you should either give SC something more or... something. I just see (very simply) T1 being worth 2 upgrades, T2 being worth 6, when I think of them in scopes of power.
Weapon Mastery: Are these 3 additional upgrades you can use on weapons you own, or 3 weapons you can use like Static Charge or Block the Sun? The first seems kind of weak (see my analogy above). The second is what I think it is, but then is it any type of weapon (including the rares from each element), or just the Other ones?
It still seems like the air tree has less, dimensions or personalities, then the other trees we have looked at and discussed. It's not a bad thing, just more of an observation.
