@Riot, a support main has some questions

I know the game is in a progressive state and things are changing, some for the better some for the worse but I don't mind because the game is still changing. What I do mind, is that with 800+ hours 202 levels later I still can't figure out what I, as the support can do against the majority of the things you've implemented into the game. I'm all for assassins being able to assassinate people, but when the healer is one of those people...... Soraka has to give too much to be a great choice in this early game meta Morgana cc doesn't stop Garen because he has a w and Merc treads and just 2 shot my carry even after the q hit, e, and trying to r him off to no avail Pyke has the worst hook in the game and can't really "support" in the sense of peeling Sona has such high Mana costs if you fall behind in items you have no way to get the money to catch up Nami w is still arguably the best heal in the game because she can poke and heal (2 people) Leona can't tank with your true damage fetish (or she can, but way less effectively) Janna shield is too expensive for how short it lasts now (I'm fine with the shorter duration but lower the cost by like 10-15?) I'm okay with Lulu right now no issues there FIX KARMA FFS what is her purpose? Cc? Nope. Poke? Yeah.... Until they decide to all in you and kill you because your shield SUCKS still not gonna address zilean as a champion off of personal preference, no offense intended to his creator but he's weird af Bard.... I'm not gonna lie that champ fun after Tahm kench is WAY too hard to kill for how much damage he can do Brand shouldn't be able to do that much damage with just a spellthief... Seriously lower that passive early game at least it's oppressive Lux is worse than teemo with how evil she is all this "SCORCH!" ult every 15 seconds, lower the e damage a bit early to champs at least Zyra has this issue of "my plants are taking your cs and I can't stop them" Nidalee should appear as a support as well please, she's very good at it Blitz kinda feels like a hit or miss entirely reliant on your team comp Braum literally depends on his adc to have common sense and decision making capability which is hard in my elo lol Thresh: STOP BODY BLOCKING MY LANTERN ENEMY TEAM, LET MY CARRY GO HE'S ALREADY 0/7/5 AD supports like pyke (or any off meta thing) don't really have items that are useful to help people, please make some ad support items with actives that are supportive, like the move speed aoe item Orianna can go in supports too please, I enjoy her ever since that box gave me that epic Gothic skin Nerfed all the supports and their items but buffed damage? Make more support items to compensate please. And my buddy Rakan? MAKE MY WAY UNINTERUPTABLE PLEASE FOR THE LOVE OF GOD! STUCK IN THE ANIMATION FOR LONG ENOUGH ANYWAY like seriously the animation is super long, and he can be displaced??? QOL change please thank you Alistar? Lore buff please And finally IVERN ........

Anyway if any Rioters actually read all of this, firstly I'd like to thank you for taking the time to do so, and secondly please inform me on how likely any of these changes are to actually happen. Thanks for your time, -Anti
