Bramble overnerfed

[GreatGonzales]

That being said, I probably agree that the newest bramble is not the "ideal" bramble, assuming that bramble changes are limited toggling thorn hp, wit for kill return, and thorn attacking. One option that hasn't received a lot of attention is:

1. 3 hp
2. No wit for kill
3. Cannot attack

I think this might be a better version of the bramble than what we have currently. Though, I don't know, then we're back to spawning heavies and snipers all the time...but at least thorns can't overwhelm unit count.
