Hey if someone explicitly says they're not good at a certain lane...

Chill out and don't expect them to be pro at it.

I'll be honest here, I suck ass at top lane. At least acknowledge that, or give me a few tips or ping communication so I know whether to group up or take an objective. Don't leave me hanging.

So yeah, people might suck at certain roles, but don't get on their case (to an extent, of course). Help them out or something, or understand they need to play a little more passively than someone comfortable in the role. Or switch roles with them. They're going to be bad (yes, I said it) at times, so at least try to understand. You don't have to switch roles with them to compensate, but at least know they suck at a lane if they explicitly say so.
