This has come up various times over the chapters, but the core has always been the same.
They are pretty weak mechanically.
They don't even have creature weapon profeciency, making it so when they attack enemies, they get AOOed.
This oversight, in particular, ought to be rectified. :)
For 43 summoning points At level 7 they do v.little damage and are essentially fodder for emergencies
This should be fixed - they should be pretty decent now.
