Is it just me, or is fighting a spirit in the astral actually -easier- than fighting it in the physical world? Most of their powers are Physical (like engulf or energy aura or whatever), so they can't use them in astral space, and so they have to rely on Force/2 bashing. Meanwhile a mage can still chuck stunbolts at them, and since they don't have Counterspell...
It seems counter-intuitive since the astral plane is a spirit's natural habitat.
Also - has the rule that all spells cast astrally do Physical drain been changed in 4th? I can't seem to find the rule.
