If we're talking Vanguard and Infernal - the 1v1s have the secret sauce.
If Celestials get squared away the game really might be onto something.
But I hate admitting this, because they screwed their backers, especially the ones who backed it for singleplayer, which I would imagine is most of them.
Only matchup I "figured out" was IvC because you just play super aggressive with mainly Gaunts and some Brutes and then Celestials lose.
Funnily enough did much better vs Vanguard than against Infernal. Mirror matchups seem to just fuck me up.
