I would like to open that topic after watching this video from Maximilian Dood.
He was making the same mistake several times.
What was his mistake? Trying to special grab (Prophet Bane) after a corner Truth Seeker ender > Grenade > flip out LK (> Prophet Bane).
You can’t do that, otherwise the Grenade will blow up in your face.
flip out LP/LK > Prophet Bane
1 shot Carabine > Prophet Bane
So, if you have seen or if you know Arbiters’ recurring mistakes, and know the solution (even better), post it here so we can improve all together by stoping those stupid mistakes
