Why are so many people complaining about autofill? What about banning a role you dont want?

The system for queues is not even complete yet afaik. Pretty sure riot mentioned that they were going to add a feature that would let you pick your two main roles and one role you do not want. I did not hear anything about them dropping that feature so it should still be in the works. Honestly I do not understand why people freak out so much over being filled into support. It is honestly one of the easier roles to play, but not many people will compliment a support compared to other roles.

My experience with the support role: Speaking from personal experience I find supporting in LoL to be a bit more fun compared to Dota 2 supporting. Supporting is one of the easiest roles to learn imo, but people tend to forget about the support more often. It is quite bad if people only play one role and refuse to learn or even try other roles. Originally I found jungling to be a bit harder and I thought it was not the role for me, but now I am currently a jungle main. To be a good player you should be able to be more flexible, meaning you can play more than just one champ and you can play more than just one role. Being able to play at least 3 or 4 roles is pretty good and it means you will be more likely to get a role that you know how to play. The one role I struggle to perform really well in is adc, and I almost never get filled into that role which is great for me.
