You last pick!
Now I don't like playing Jungle or Support. I just don't. I never have, nor will I ever. I have no investment in these roles, nor any incentive to learn to play them. I just don't find them fun.
So I've come down to always dodging whenever I get forced to play these two roles.
Why?
Why should I play something I don't enjoy? One plays a game for fun, and if you're not having fun, then that undermines the point of of playing games.
But why don't I enjoy these roles?
Because I'm not a punchbag. Nor am I a scapegoat of blame for other people's inability to play. By far these roles are the two most abusive roles because, naturally, if something goes wrong it was your fault because you didn't gank a lane that had over-extended themselves, or didn't ward XYZ location with your infinite supply of wards.
Whenever I play these roles, I just come away with an acute sense of failed suicide, so I refuse to play them. I think that's reasonable enough.
