Get rid of/Rework Support
I don't really have any ideas as to how to rework the whole concept of a support, but I'd say it's inherently toxic. Every other lane and the jungler's performance depends on one thing: themselves. Bot lane depends on the performance of someone else. Whether its the ADC who rushes a
or uses all his skills to cs yet is still behind by than more half of the enemy ADC or the support who takes all the CS, misses all their skill shots, or doesn't ever actually ever try to help the ADC in trades it subsequently hinders your performance compared to being by yourself. It's just frustrating to be in SoloQ and get paired with a crappy laner because I was last pick and didn't get my preferred role. That being said, I'm not complaining about that. I'll do it just fine. I just think there could be something better instead.
I get that it's a whole meta thing, and that the meta can shift at any time but with how hard Riot has been enforcing it I doubt it ever will without change on their behalf.
