it seems like all ai tyranids think they have jaws
causing most of them to rush forward ramming themselves to death
if possible it would be good to have a distinction between jaw nid and gun/torp nid ai so that only the jaw ones rush to hit and the others just rush to get into 2k

also a lot of escort ais ram themselves to death without triggering spore clouds
humans dont have the reaction time for that
but it would be an interesting buff to compensate for ai stupidity to let them do that
