I had tried VERY many different settings in u4et mutator with no luck. I didn't think to reset everything (pretty much) in u4et to default. Ammo boxes abound now and I can pick em up I am one happy camper... ahem
as for playing the wizzard class against monsters, I have found a way... I am using a monster generator mutator (monster arena for example)... It's a bit funky but I just wanted to spend a few toasting some skarj... now to try out the classes proper (no monster mutations).
