Reduce the overbearingness of stunmeta

[NightmarechaMillian]

I know this is a (pretty) dead thread, but I and a few other coders (couldn't get a dev to weigh in) seemed to all agree that a 1:1 damage received/stun reduction change would be pretty good.

That having been said, since classes are back up in full swing, and I've got my hands full with ghost sawflies and surplus ops, I don't forsee myself adding it in the near future. If anyone wants to pick this up, though, I'd support them and give advice to the best of my ability.
