Please decrease the amount of mobility in the game
No more dashes, no more blinks, no more large movement speed increases.
Just once I'd like to play against an immobile team. It's even a pain in the ass when you have extremely mobile champions on your own team, as their mobility just removes all need for skill, thus making the wins you get empty and worthless. Getting ganked? No worries, use a dash! Misplay in lane? Derp lemmie just dash on outta there scot free. Get caught out in the jungle? Oh well, I'll just dash over this wall, see ya suckers!
People are getting one too many freebies by playing champions like Zed, Ezreal, Leblanc, Yasuo, etc. who are very low risk/high reward simply because they have more ways to get out of a bad situation. Not only that but it's unfair to people playing Karthus, Varus, Jayce, Teemo, or any other champion who lacks mobility. If someone asks "hey, why do I never see X? they're really good!", the most common response is "they have no mobility".
You only have so many bans, and as someone who loves playing immobile champions and couldn't care less about flashy plays, it really pisses me off to play every single game against a champion with 2 or more dashes in their kit. Even 1 is too many on some champions (e.g. Ekko, Ezreal). I really think the game would be in a better place if mobility skills would be kept to an absolute bare minimum, with only a select few champions having access to a dash (and almost never having more than 1).
