I don't really like this list... Also,
IIRC, guide only affects
your units, doom is another story entirely though...
Farseer, drop the runes of witnessing, if you really want to keep them w/e
Fire prism, take two or go home, but seriously, try to fit another one in if it's available
Jetbikes,
MEH
Serpent, get those vectored engines off there, you move fast enough already
Storm Guardians, these are in the serpent, right?
Spiders, not enough to do anything effectively... drop them for some warlocks to add onto your jetbike/storm guardian squads
