$10 respec is overpriced imo compared to the trial/vet/freespecs/recipes that will still be availible and coming out. I would be ticked if this option replaced issue freespecs but since it doesn't I'm not.
This compares to character slots, wedding pack, server transfer, rename and all the other administrative stuff they've made available for purchase over the years. It has little to no actual impact in how you play the game. It's not some uber power or something that gives you a leg up over everyone else. It's not a level purchase system by any stretch of the imagination.
Altho for $10 they really should give a respec to every character you have or make i.e. you buy a respec, you now have a single respec on all your chars and if you make a new char he gets a respec too and so on. New players who don't even have one vetspec and don't know about or want to do a trial respec can now have this insurance.
