NEVER let a support main autofill
Yeah tittle , don't let a support get any other role more than support , i don't want to have 2 support mains in the same game specially with the lack of supports in ranked.
What will happen if a support gets autofilled
1:He will feed hard af in lane
2:He won't feed but will be pretty underfarmed and the enemy toplaner will be farmed af
3:He may have done well in the laning phase to our jungler help or the enemy lane playing poorly but he wont know how to rotate well anyway so he will
start getting behind pretty quickly
However the first case is the most common one.
Now all that i said is only applied to high elo , i don't think that a support main will do too bad in any other lane in low elo since ppl can capitalize that hard on any1 else mistakes
