Can they perform other roles? For example, form a line of defense around the psion, throw things at them, collapse buildings, etc? Can anyone dispel the protections? Can anyone TK a PC into smacking into a construct, thereby removing the protection vs. that one construct? (Okay, that last one's a little cheesy). Or could you just do a literal rules-reading on them?
