I think it would be pretty neat if instead of just amount of items to spawn there would be a configurable % chance to spawn for each item you place in the loot table.  1.0 being 100% 0.1 being 10%

that's a good idea, I'll consider it

i made another post but i dont see it as an option, you should allow diffuculty to be added for maintained events like having 3 easy 2 medium and 1 hard base rather than random. and possibly the ability to force wood, stones, metal HQM to be in the TC
