keep in mind that shards were buffed.
From my own experience i remember chasing air units with shards cause they are just THAT fast
also not 100% sure but also running away from torpedos
dodjing almost any projectile
Even if you don't manage to completely run away from torpedos, you still greatly prolong time before unit dies and usually at that time torps are right above your aa boats... tho they still kinda don't feel that great against t2 torp bombers, tho you really need to take unit costs in account if you want to understand how good they are
