IT IS THE SAME FORTIFICATION SYSTEM but instead of fictitious objects it is fictitious characters. You continuously saying "artifacts are not allies" means literally nothing in this argument. Plans change. Stop using crappy analogies to argue a point that you don't have. If you buy a full style set of tank gear you get a discount on that same gear for any role. If you buy tank augments but switch to healer you are allowed to feed those tank augments into your healer augments. If you buy tank artifacts but switch to healer you are allowed to feed those tank artifacts into your healer artifacts. If you buy tank allies but switch to healer you have to start from scratch. That's why people want to get it changed. DUH.
