I can one hit through force armour, a good Shadow Infil can pop a 4k+ Project 4k+ Breach and a 3.5k+ Shadow Strike, that's 11.5k damage including the two Clairvoyant Strikes it's 14k+, then with the Shadow Technique Effect hitting it's 14.5 - 15k Damage, that's one shadow, and that's a 7 - 10 seconds rotation.
Shadow can use the SCSH tactic, they can also push people away.
I'd rather be one of the two shadows than the Healer or the Tank.
