Nevermind I fucking did it, the solution was so simple I feel stupid not figuring it out sooner.
if anyone's curious
first strat
>have one White Mage, Two Black Mages and a Knight, the Knight stays in the front row while the mages nuke stuff and white mage heals - this invariably led to the Knight getting killed with Blizzara almost instantly
What I hadn't realized is that Blizzara targets all party members in one row and it does less damage the more it splits up, so the new strat was
>two Knights in front soaking up the physical damage and splitting the Blizzara damage, one Summoner group healing with Sylph and a Black Mage either nuking with Fire or healing with secondary White Magic if necessary
