First of all, I'm not talking single rouge.
Well I
was, and that's actually more relevant when discussing Warfare.
You can destroy physical armor with 1 char and then CC with another, potentially in aoe.
Or you can destroy physical armor and CC with one character and
one action instead of needing two characters to do so.
Alternatively you can simply outright kill something at range with Ballistic Shot + Barrage or auto attacks.
Secondly, you can easily destroy physical armor on non boss enemies with elf rogue if you use flesh sacrifice and adrenaline cause you get 2-2.5(backlash or flurry if within the pawn range) hits and then use your CC. 20% less damage won't change that.
Yes it will, especially for Battle Stomp, which again doesn't crit. I know how to kill single targets with a Rogue, and that's not what was being discussed. Backlash > Rutpture Tendons > Chicken used to be able to take out any non boss enemy in the game and was the go to combo for about half of the game. I don't know how it is now, but that's how it used to work. The first two hits crit too, removed armor, and it was using single target abilities, which deal more damage by default anyway.
As for mage mobs, my rogue was just killing some of them in 1 turn with adrenaline late act 1 (yes, on tactician with no LW). The only thing you need to ensure is that you have level appropriate daggers. I had some problems in the damage department earlygame 2 until i figured you shouldn't be running with level 1 weapons at level 4.
What exactly is being argued here?
