Guys, come on. Max is a blacksmith. A magical one, sure, but a blacksmith nonetheless.
His martial training is about shooting orcs from an helicopter while blasting music from Gotri's runic boombox, not going to the outskirts of hell and fighting daemons.
To say nothing that we have a superbly interesting magical sword, and a gold wizard who wishes to specialize in making magical swords, and are about to lose access to it.
We haven't commited to going, why send our precious underlings there? There are battlewizards and plenty of other magisters to try and draw from.
