Alright, we've all seen other MMOs that have equipment with slots in them, and after looking at this game's solution to upgrading gear above it's base stats, (see: UVs), I think that having it 100% based on a low proc-rate is a really terribad way of doing it.
Now I'm not saying get rid of those procs altogether, I think we should keep them in, just keep the effects lower so that people don't have to "Ragecraft" because they feel like they have to have the BEST possible UV for EVERY piece of gear in their inventory.
