Well that makes no sense.
You have to start somewhere ...and it doesnt matter if you are level 1 -5 or level 10 if its your 1st time playing a support then you are not going to be familiar with the role or that champ.
I think this is what causes a lot of the rage you see when people hit level 30 and start to play ranked.
If they are giving 10 chams as starter champs then i think at least 2 of them should be actual supports.
Though i know Ashe secondary role is support but most people dont even know that and look down on it when used.
Ive seen epople rage and want to report because it was 2 addc bot and both wanted to farm so they report each other for stealing each others farm lol.
