A Yasuo change that not only makes sense, but also is rather fair to the champion.
Make his E damage physical. Don't nerf the damage, just make the damage physical damage.
Why? You may ask. My reasoning behind it is this:
Most people have a full set of Flat Armor Runes.
You know, the ones that give you 9 flat armor at the beginning of a game when you have all of them? Those actually do a LOT of work early game.
Yasuo currently Maxes E first, as the base magic damage is high, and essentially makes him a mixed damage monster. By making this change, itemizing only ARMOR early game negates a good amount of burst, especially from the surprise magic damage his E has. This will make him easier to itemize against, and will make the cheapest runes in the shop negate a good amount of damage from all spells.
I mean, it also makes since from a thematic perspective, right?
Why does a guy dashing around like that deal MAGIC damage. Makes no sense.
Also, this will reward better Yasuo players instead of crappy noob ones, as people who land the Ultimate as Yasuo will have the Armor Pen from his ult passive, which will increase the damage his E would do.
Just my Two Cents to the Yasuo discussion.
