I am a support main but sometimes I do enjoy playing in other roles. It's just that I can't put fill or support as secondary otherwise I get those roles almost 100% of the time. The alternative is adc only, which takes its time as well.
If I choose to play jungle (jungle primary, mid or top secondary) it takes an infinity to find a game... today I reached 20 minutes with these roles.
Does it take this much for everyone?
