1st 30% is pretty much the same as 100%... prof can just spam the dispell....therefore i say 5-10%
2nd 1-2% destroy fcp, sounds fair to me
3rd stave crashers penetrate pneuma by a %, not 100%...or else why should people pneuma in the first place? I say...30-50% /ok
my two cents :)
oh, wait. there's another penny in the pocket, so make it 3 XD
