I've been using MageFu and like it. However it has some problems, like disabling it self so you have to reenable it every time you log in. Also the buying of reagents doesn't seem to work. And you can only trade 1 stack at a time using it's trade method. And the messages for portal default to /say and am unable to change that (probably could editing the code).
Just mainly wondering if their is another Ace2 addon that does similiar stuff (Quanjure isn't Ace2 yet is it?)
As far as the reagents I had a problem as well. It buys them according to stack not an actual number count. It wouldn't buy them for me at first till I realized that it wouldn't because I was broke :) Anyway try to adjust the stack to the lowest and try it. That worked for me.
