The enemy ADC is killing my 6 item Mundo through ult in ~3.5 seconds

Video?

Hmmm that's odd, looks like you didn't have a deadman's, you had a chain vest.

I also hopped into the practice tool, and I call super bullshit. On a 100 armor target I was able to deal 5k damage after 5 seconds. Your mundo build had 4.8k HP and 230 armor, 130 more than the practice dummy.

I copied both of your runes and masteries to the dot.

So you are going to expect me to believe, that an Ashe, who takes 5 seconds to deal that much damage against a 100 armor target while standing still, dealt 1.3k+ dps against a mundo with all that bonus regen on his ultimate, while kiting you, with 130 more armor?

Ok.

or , depending if you really wanna shut down the healing or just deal more dmg. Means less crit in the build. But damn if it doesn't shred tanks.

You just have to finish the game on time. ADCs and sups were overbuffed over the years/

Gargoyle stoneplate or whatever it's called will solve this

I'm calling bullshit. A minute or two on the practice tool shows that you're lying.

And you can't even blame lucky crits, because you were against an Ashe. She cannot have lucky crits.
