I don't understand what you want. And tbh Soraka was always lane bully in past, right now she is least lane bully ever (mostly due to the overally high dmg, ignite buffs and meta shift). And the hit Q to enhance healing is already a thing. So your post makes no sense to me...
But yeah the Riot's changes on Soraka and there has been many were really weird...
Anyway you can't bully anything in this season because:
- you would have to max Q or E to make it at least bit efficient, but if you do it, 8secong cd on W prevents you to win extended 2vs2
- you can't really poke with E unless enemy is stupid or weak enough to not punish this
- you must get close to enemy and use autoattacks, which allows enemy to engage onto you or trade back, and even between enchanters she just loses that poke trade to everyone including janna
- doran shield and bunch of other anti-poke runes from resolve tree that is commonly used by both marksmen and supports
Soraka is in really bad spot right now mainly due to the overally too high damage (you can't heal oneshots (and by oneshot I mean kill with in 0.x second no matter how many abilities were involved)) buffed ignite (no point wasting ult that was nerfed its previous ability to remove GW for a target with 10%hp with ignite on him) that is now commonly used in toplane and the general state of meta (high ammount of snowballing in sololanes, every second game decided in first 15 minutes, huge impact of junglers).
S5 Soraka was defnitely obnoxious, the rework was great in fact despite Soraka mains claiming opossite she was very powerful at that time which was discovered in s7 by pros, suddently "ardent meta" (and I won't stop claiming it was overrated and overreacted) happened and Soraka received minirework (which wasn't exactly bad) as previously Q slowed only in small sweetspot and while the instant heal from Q hit was changed into delayed hp regen the benefit of Q slowing everytime was worth it. Then came unjustified R nerf, and W nerfs because Soraka players were suddenly maxing Q (which I was doing since s6...) to be a lane bully and that wasn't allowed for Soraka.
Imo, Soraka needs two things:
- remove R nerf
- rework E or fix the issue with silence not applying instantly, every second game I lose critical teamfight or shutdown because E doesn't work and enemy uses flashe or spells after they came from tp/zhonya/other easy-to-counter ability like lissandra E while standing in perfectly timed Equinox.
That is all needed to make Soraka not feel ultra terrible again and be balanced no matter what meta shifts happens.
