Best Dual Threat?
For BGs
Red Skull might be the best defender of the bunch, but Guardian handles more meta defenders than him. Also I imagine at higher sig, Guardians critical damage resistance can stop a lot of nukes that bypassed his autoblock.
Also on a side note, how does everyone like the Guardian vs Domino matchup? On paper he should work well, but she can fail his crits, charges, and shocks to mess with the matchup
