Arena Mode - remove useless drops

[daftigod]

Vision runes, pickaxes, and wands of illumination are all I can think of right now, but I'm sure there are more. I'll edit this thread if I find/remember others. It would serve gameplay well if certain drops were barred from existing so that they could increase the player's chances of finding the good stuff.

I had another idea of some kind of a rotation for drops too, one that would guarantee at least one useful item for that each class every X amount of drops. Organize the items by class type, or more generally by melee/ranged/caster/hybrid lists, and force the engine to pick from that list every 5th -10th drop. Or you could use that list of items exclusively for the entire life of the character, but this might make it too easy or not random enough. You could reduce the total amount of drops (and bar enemies that can split from dropping items) to balance this out somewhat.

Anyway, I'm just trying to give some ideas for reducing the frustration of some arena plays. Sometimes you can go 60 waves with your basic weapon or armor, or not get a single helmet/hat, and other things like that. If the item list was narrowed down to a degree it would help. This isn't a huge problem, and has gotten alot better over time. For example, with b42 I think I've been able to clear the arena with 6 different classes. With older betas the arena seemed to favor certain classes and that doesn't seem to be the case anymore.
