We have over 140 champions in the game, but Zed is somehow in every single game. Sure he looks kinda cool, like Shredder from TMNT, but the real reason everybody mains him is because he is incredibly easy to use. Everything is point and click, and his 1 skill shot is fast moving, huge, and is mostly used from point blank range when you point and click ULT onto someone, right click them, and then teleport to safety.
Here is a description of how assassins are supposed to fit in LoL: Assassins specialize in infiltrating enemy lines with their unrivaled mobility to quickly dispatch high-priority targets. Due to their mostly melee nature, Assassins must put them themselves into **dangerous positions** in order to execute their targets. What is dangerous about Invulnerably teleporting up to a target (without aiming anything), nuking them, and then immediately teleporting to safety?
But Bear, what about the elite plays with all the shadows? Gimmick, totally unnecessary for bursting down high priority targets. I would love to see emphasis on rewarding Zed players who are skilled with using their shadows offensively, but sadly it's just not important. Can be a useful skill once in a blue moon, but hardly essential for becoming an effective nuking machine.
I think we can all finally admit why everyone is a Zed main.
