I like it. A lot, a real lot.
The ability to use a skill really diversifies the game.
It gives single minion familiar users a lot of ways to customize their character. Use evasion vs PL vs archer vs bloodlust tank.
What I do not like is the relative scarcity of these amulets. I would like to see another 50 put into auctions. I see a few in rentals now and that really upsets me. The first set should have been for people who would actually use them, not for speculators to resell or rent.
However nothing could be done to prevent these things from occurring.
The lack of using an AoF with the familiar is something a lot of us knew would happen. Or at least change. I believe now things are a bit more balanced, moving towards minions over familiar.
However, these are my initial thoughts on the AoJ and are 100% subject to change.
PS: Can we get AoJ added to the dictionary?
