Seraph's bugg on autoatk timer

I noticed on ezreal when he casts his spell (so he should regain 20 mana) and then autoatks around the same time, he still ends up with just the 20 mana. So its giving the +10 from autoatk and then throwing the 20 from seraph in but somehow it ignores the mana from autoatk then and its just 20 gained instead of 30.

Also yasuo ult is bugging all over the place, not doing the dmg it should or rarely even none at all. Tons of spells do dmg if cast while dieing while alot others don't, makes 0 sense. the range of autoatks when champs focus a singed seems like halved, I've seen ranged champs literally continously walking in his melee range just to autoatk him while they got atleast 2-3 hexes range.

Just to name a few anoying ones of the ton of buggs currently in it that I've seen. It's absurd to be honest, shouldn't even have release ranked in the state it's currently still in.
