Seeing hige client side delays with stable ping and fps. Do I reinstall or stop playing?

What a shitty piece of software Riot created for preseason. Champs with free phantom dancers, extra time to do a single auto attack. Mesed up range calculation. Dashes going twice the distance. Name a feature and it has a bug. Healing preventing additional damage. Invulnerability happening instantly blocking applied on hit damage. Out of sync servers causing games to crash intermittently. This game needs rework now. Tear it down and build a new one. Don't let your skin meatballs carry the dish. The spaghetti is bad enough.
