Regarding ESAM + customs jank, the narrative was that the pros don't like them and feel they're going to make the game more random or give undeserving players wins. We've seen that customs barely effected top 8 placement. Pretty much everyone who we thought would make it to top 8 did: Zero, Nairo, Mr. R, Fow, ESAM... that the other 3 were a good Sonic, Ally (a top PM player) and Abadango is hardly an upset. If customs beat players who aren't as good, all that means is people need to learn more matchups, and the standards of play will go up. Nothing wrong with that, on its face. The standards of play for Melee are much higher and that community hasn't been negatively effected. Learning how to deal with a custom is easier than spending a year to consistently wavedash/land and l-cancel under pressure. Nothing about EVO gave me the impression that customs should be thrown out.
Sheik is already so hard to play that the tier whores who played Diddy in the prepatch days by and large haven't bothered to switch to her. It drags to 150% when the other player doesn't make huge mistakes and knows how to DI.
Outside of a global nerf to rolls there will never be a roll nerf. Sheik is a ninja-style character. Nerfing hers in particular makes no sense.
I like this zinger but I'm going to be a debbie downer and point out there are many characters who can stage spike people with their up b's.
What makes them strong is how fast they are. If two characters react in the air at the same moment, Sheik's hits first outside of a few character's nairs. Her aerials already trade all the time, it's just that she has the speed advantage. If her fair came out on frame 11 like Bowser's instead of frame 5, no amount of priority would make the move good.
When it comes to tiers - there are certain characters who lend themselves well to being played at a high speed. Those characters find themselves at the top of the roster. Good frame data beats bad. Diddy is the perfect example. Despite all the nerfs, Diddy still has top tier frame data and thus can be played at a high level - with the speed of a top player. This is just the way Smash is. I want the slow characters to be as good, but I don't think that's happening.
