I didn't call it P2W, I find that kinda silly. P2P. Meaning you buy it you use it (VIP perk is nice, but you still have to pay something to use it).
To me when I first read all the Harper tree features it immediately screamed ARTI. Yet Harper as such brings me an image of caster/bard. This tree is full of things that'd enhance both ranged Arti or Juggernaught type builds. Heck, it even seem to have better Arti pet enhancement then Arcano.
