We have "marksmen", so why do we still have "supports"?
I hate the term "support". Just like how "marksman" is a more fitting term than ADC, I want to see "tactician" or something similar take it's place.
The best "supports" hate everyone. The enemy team's attempts at having fun is a crime and your vengeance is doled out slowly over the course of a match. Often times it means saving your teammates from themselves; occasionally you have to claim the bounty from their murderers; primarily you personally shepherd your enemies onto the path of ruin.
Ultimately your machinations culminate into a creditless victory that merely serves to fan the flames that fuel the war on their enjoyment.
"Support" is just one of many tools a successful tactician employs. You wouldn't call a carpenter a "hammer" or an artist a "pencil", so I hope Riot does the right thing and drops the "support" label and replaces it with something better.
