Ok, so Arcanists have to take 3 feats to get the same benefits that a Mage gets for free AND they have to give up their Implement Mastery?
Yeah, sorry...doesn't seem like a fair trade to me.
I agree. 3 feats plus giving up your implement mastery is an extremely steep cost, especially considering 2 of your heroic feats are probably taken up with expertise and either unarmored Agility or Leather Armor as it is. Why not just be a Mage...
