any ideas for off meta lanes/builds that are fun?

Melee carry bot lane.

Master Yi/Xin Zhao mid.

Roaming Blitzcrank/Alistar

Depends on your idea of fun. I prefer doing off meta stuff when everyone is doing it. The big two I'm looking forward to trying are team Bronzodia (shen, malphite, yi, amumu, and blitz) and the Demacian five (garen, jarvan, lux, galio, and xin).

zyra + yasuo bot

the level 6 is absolutely halal

pre 6 zyra can 2v1 anyways

Blitz support Thresh adc, double hook profit.

with 15% crit runes and 5.5 AD. Then build . With 100% crit, you basically are multiplying your damage by 2.5. They are dead by the time fear runs off :)
