All still makes psylocs a spell without a book... and yes, IS can have a place, but its a lonely one in the corner....
Ladin, I do sometimes forget to pass when outnumbered, so yeah, IS could have more play. But really, in the global meta, are we seeing the IS and FM slaying it? When steelclaw or others are the buddy of choice... in fact people mostly debate the value of any mind school creatures, then something is wrong. If AW playtesters were regularly romping the wins with their clever, 'stalker' school books, then I'd suck it up, but its a pipe dream that old timers tell about their time at band camp... let me tell you, there was no pipe or pussy, just smoked stalkers.
