Improvements to my Arena team?

Double tank combos are ok, but I don't like a Shore + STH combo because when both taunts are up, the attacker will always choose to hit Shore so as not to give additional TM through STH. IMO, Shore + RG, esp under an EP lead, is better because they just provide an absolute wall of health. Or you could combine STH with SF, so an attacker would have to make a difficult choice of either triggering an SF counter or STH TM gain, but can't avoid either entirely. Facing either of these combos would almost force a would be attacker to use B2 or really micromanage a QG/EP attack combo.
