Dynamic queue is unfair to support solo players
Teams who play together almost always put their weakest player on the support role (or adc role) with easy support based champions like janna, sona, ashe, jhin that are good even if they are really behind as long as their team is ahead.
Then because of dynamic queue, the mid+toplaners of their teams get super easy snowball lanes to "compensate" for the lower average elo of their team.
As a support main, I almost always win my lane but it feels like 60% of the time it doesn't matter because top & mid are feeding. Then the super fed midlaner roams bot all the time or the toplaner TPs in and they bring their advantage to botlane.
I think it's totally unfair. There is no way a botlane can snowball and roam as hard as a toplane or midlane (mostly because they are lategame scaling). It can work if your ally happens to pick a strong early adc like lucian but if they go say ezreal into a lucian there's no way you can influence the game heavily within the few first minutes. Also, if you can, you will have an extremely underfed midlaner (who of course went zed or another midlaner without cc) who is thus completely useless while THEIR botlane can setup easy kills regardless of their items.
To me the perfect solution would be that teams can either duo bot OR only play top+mid+jungle OR only face teams that have the same composition as them. Either that or the average elo of the team is replaced with the highest elo of the team for deciding which teams to place against each other. Another option would be that the elo's of the support & adc players are just weighted lower than the rest.
Either that, or I should just find a midlaner buddy to play with whose a league higher than me...
