I just argued with a Diamond Player...

...about the nature of Lee Sin's ultimate. He claimed that the counterplay was to "flash while he's channeling the kick."

I argued that no, Lee has a fraction of a second of a stun before he kicks to keep his target in place, making flashing out of it impossible on its own. He also called everyone in the game who died boosted or retarded, as a side note, so there's that...

I thought Diamond players were supposed to be knowledgeable about the game? Any Diamond players, help me with this one.
