Get rid of the win-button skills.
If you can’t run, face them head on. A lot of these hundred blade user’s are glass cannons. I’ve only played warrior exclusively in PvP and use a sword and shield and have no trouble dealing with these players. I do get beat by them every now and then, but I don’t expect to win all the time. If I want to get away from a fight and they keep pinning me down, I think to myself, “Alright well running isn’t the answer.” I begin to attack them head on and by using my shield and utility abilities combined, I’m able to block their “OP combos” and destroy them while they’re waiting for their cooldowns. I too use abilities that make it so they can’t run so when they come at me and fail, it’s their turn to try and survive.
The two warrior shield abilities (don’t know names off the top of my head) really help counter these bombardments of fast attacks. The 4 ability for shields interrupts them and 5 blocks.
