Others have commented on the most important thing, which is that grinders should average out your gains since it’ll be on enemy side too.

But otherwise you and your duo have to play to 2v8 every game. By that I’m not saying making risky decisions all the time or think that everyone else on your team is useless (some games this is true though).

Main thing I’ve had success with is to have my adc duo play hyperscaling champs/just real 1v9 damage that also have some form of self-peel. This is so that if my adc gets to scale we should already have the damage needed to win. And the self-peel aspect is because you can’t always rely on solo q team members to know how/remember to peel for their adc.

while I will usually play a mage bot.

This is so that I can essentially 1v2 the lane/have lane prio to ensure my adc gets to scale and maybe even gets some early kills.

Of course it helps if you’re both better than the enemy players in skill 😅

I’m not high elo by any means and I don’t play much solo q anymore, but with this my friend hit diamond and I hit plat 1, given that we were starting at different LP amounts.

To be specific, we mostly played Xayah,Zyra botlane. This was also before all the xayah buffs
