I want Stormraiders Surge back and my Spellthief on hit speedboost back

/AP Sona player who cannot trust Seraphs/Zhonya and Banshees for my defenses because regardless of my defenses I will die due to a gapclose/flash + insane damage

I could trust the ramp up in speed, it has saved me so many more times then the above 3 items I have mentioned

Why has Riot completely extinct the option for immobile mages to access bursts of speed now?

Can we please have the old spellthiefs MS boost on spell hit back on a new AP item? Can we revert the useless Phase Rush into the superior but still outclassed Stormraiders?

I had never heard complaints about the MS boost grating abilities of both these abilities, they completely just deemed that mages should always die if anything jumps on them in preseason, then didn't unfuck it
