Soraka - The most tilting experience
Not the first time I've been here but gonna make it short.
While I have found Soraka getting increasingly annoying to play against there are things that along with the rest of the game (Tank dps > carries dps > assassins dps - cause balance) that aren't fun to play against and add nothing to the experience. While there might be counter play to one area there is nothing you can do against the lane other than hope your team are willing to co-operate with you... assuming the enemy team isn't doing the same (illaoi, who am i kidding even ganks don't help). But in my last game it hit hard when a support joined me in my salt-fest about Soraka and the terms "Soullink Warlock" (for WoW players) and "spirit master" (for Aion players) got brought up. It made me realise the futility of playing against the champions and how linear these champions really make gameplay, just like an AI in an mmo. You're forced to face the immediate threat while ultimately your efforts (and resources, such as mana and cooldowns) are wasted to their healers. They can focus on a single ally, essentially treating them as a pet toggling between; giving them/infusing them with health > and draining health from the opponents > using light cc when things get rough > repeat. Describing Soraka like this shouldn't be possible but is, and it made be realise just how simple her gameplay is and how simple it is to play against it... which is just don't (passive mobs always live through your dungeon runs).
But throwing around salt is impolite (thinking solutions here) so here is one suggestion which I think could make a huge improvement even if its only temporary which is; remove her sustain while removing her infuse (or even better remove the champion :D) since it means that... well... poking her has an impact. Her q is easily avoidable at max range but that's assuming you're not going to farm, the attack animation is long enough for soraka to pop out of a brush and pop a q on top and this is even more prevalent in teamfights. While on the other hand her infuse feels underwhelming until its spammed, While another fix for this would be to make her even more of a warlock and make her w a healing over time (working much like old karma soul link connection) however that would be a drastic change and we're not talking short term with that.
Overall this is one of many champions/items which as of right now infuriate me in the current game state and while I'm sure people will say "You can't do a better job" I'm one of the (roughly) 30 million daily users who play the game and together we, as a community, can. the game shouldn't be based around the 100-200 professional players any more and while esports is great it shouldn't let its greatness drain the healthy, fun parts, of our game... like laning... laning used to be fun...
