Given the current prevalence of heavy abuse of spam and cheese tactics what is going to keep breach from becoming a mode plagued by team comps that apply the most broken attacks. These comps already rule dominion so what's going to keep them from doing the same in breach. I think faction locking breach would help.

I should note the king seems very slow and thus easily parried so against a deathball and spam comp he is going to get melted even with a large health pool.
