Try doing silly 1v1s!

No hard rules, but basically, it's 1v1 and it's silly.

You could use standard rules (first blood, 100 cs, or first tower) and play silly picks like Janna, or play something dumber like playing with a bot and trying to feed them kills (getting a kill yourself doesn't count). Or play as proxy singed 1v1 and go for first 150 CS or something.

It's a lot less stressful than tryharding in 1v1 as assassins or skirmishers (or playing a real game), and still so much fun.
