You're also forgetting the last part of his UBB buff, which converts defense to attack, which is the same as Lance's UBB with a 100% conversion. With his two def buffs: UBB and SBB, 280% defense will transfer to a crazy amount of damage. As most units nowadays have around 2500-3000 defense, units will be gaining an extra 7-10k attack which will boost the DPS of your team while still being able to tank all the enemies' attacks for two turns.
