Butterwood3 votesFaced a team with a pretty good Lee Sin jungle last night. I was Illaoi top against Jax. He was completely overpowered (clearly hadn't faced Illaoi very much, couldn't seem to figure out what to do when I hit him with E), but Lee Sin set up a tent and ended up giving him a kill and 3 assists early.
Fast forward to late game - Lee had to help other lanes so I took a few kills and a turret from Jax. I'm pushing with my team mid, Lee Q's in and ults me away from my team into their turret where his team was waiting. I land a quick E on him, ult, and spam W as much as possible for a triple kill with 2 assists (ace), and my team rushes down mid and grabs a come from behind victory.
Illaoi is fun. Please never nerf her.
ZaneShadow1 votes5-Man Illaoi Ults are pretty amazing. That wack when the first wave of damage hits is so amazing.

Galiö1 votesOne time I'm my diamond promos I was wailing on the last nexus turret with a big wave and my power went out and when I reconnected my team won and I got a loss for being a leaver and failed my promotion back in season 6.
I was the most satisfied then. Lmao

Soul Dealer1 votesGoing 0/10 as jax in lane against a Warwick, then winning the game because kda is not all that matters so I just kept getting objective after objective while ww was chasing kills. I took 8 turrets 4 drags and rift by myself that game. Just goes to show kills are not everything
