I tried to make it a plausible kit to the best of my abilities. But it'd never reach the point it's at without the comment discussions. Thank you all for that.

I really didn't want to overdo it with the lore as i'm terrible at story-telling.The shorter the better :)

My intention was that enemies could get time to react yet still have that eerie feeling of unescapability since the movement speed is so huge whilst on the path. Thankfully, you still have a bit of time to look for backup if its near, or simply prolong the inevitable if you're truly isolated. It's a heavy vision play for Youmuu as he has to have enough vision to discern weather it's safe to go in, but also to have enemies hidden so as to trigger it. I'm quite content with the passive, i think it's very rich in healthy and fun game-play.

I had a rendition where instead of dashing to the target, he just summoned an appiration at the target's location to strike for him. I might just reverse to that if it proves to be too punishing to have him jump around a lot, but i feel like it's less flavorful. I intentionally made the range shorter than most marksmen (475 vs average 550) so he has less dash distance. Do you think i need to revert to the appiration style?

Yeah, the W is very vanilla in itself. I suppose it'd make for some interesting plays switching a form to get the desired type of defense.

I'm not really inclined to change the e passive (sorry). I think my reasoning is enough to warrant it, however i just like that it makes him unique. Extravagant skills give character to a champion and this one could be Youmuu's trademark :)

The active does indeed feel boring. I initially had it be a low cooldown skillshot nuke. Throwing a spectral sword at the enemies piercing the first 2 and ending at the 3rd target struck.

I scrapped it since i felt that he needed more defensive options and having every part of his damage bank on attack-speed outlined a very plausible defense route for his enemies (frozen heart, randuin). I could still go back to the nuke as it's pretty flavorful. What do you think?

I wish i could just load up this kit into a custom game to test the feel of the champion. To be able to properly deduce what's broken and what feels just right, but for now it's all speculation. So i hope the ult doesn't prove to be broken as i quite like the effect.

Professional or not, your input is invaluable. Thank you.
