Modders or just op

So I was leveling at finstern ulti and got invited to a party where we were doing 30 second runs and I thought to myself wow great party....these guys are so strong and op, 2h needs a nerf, my ele hb can't even compete
But then I started noticing they would cast gsw in a middle of an aoe or not use meteor to dodge aoe's and they wouldn't lose their gsw buffs or die.
I'm not someone to blindly accuse someone for modding but am I missing something? Whenever that aoe hits me with my gsw at max stacks I'm rip 100% of the time.
And their damage
ik 2h is really op but it's like they using 6th anniv weapons

Anyway I took a video to show what I mean



In the video I slow it down when finstern does an aoe and both of them are charging gsw and get hit by the aoe and nothing happens to them, no buff lost either which I find odd.

 

Best to report them, dev guys knows the math. And they can investigate better server side(it maybe just lag). Wish that they give incentives on reporting tho.

 

Yeah maybe it's lag and I was a bit behind but it's just many times at the start of battle they would cast decoy or charge gsw getting hit by that aoe and I can see they get hit by the aoe because their hp bars would go down, even at the start of the video I shared their hp bars go down by like 5% after the aoe hits them while they charging gsw and they don't lose their gsw buffs.
Anyway if nothing funky is going on and they op, I guess it's time to make a 2h again xD

 

A simple Google search pulls up a result for Max ASPD and God mode.

 

Yeah vive found valyze too in my case they last 50 seconds and a 2h without pierce how they do such damage
