I dunno, once had an Arbiter player come after me one time with a mass air attack (basically he had full pop of banshees) to my 3 spartanks and 6 fully upgraded (or was it five >.>..) wolverines.
soon as he engages me I drop my super cryo...1 minute after that my opponent wants me to join a party..once I do he tells me that I dropped 14 of his banshees with that cryo..couple that with a few wolverines and he's done for.
and yes I did canister shell his leader :D
I can recall a few instances where cryo really saved my but...
on the topic of vampires/hawks. you can't just send your whole army of vampires against Anders air...because guess which leader power acts like a carpet bomb for air -_-...yeah, cryo.
but then again, it needs to be at least at large I feel to really be effective. (super is like Overkill) medium is meh...don't expect it to drop entire air armies.
