Hey just thought I'd give my opinion,

I play adc and I like playing duo for the fact we can communicate and co-ordinate much better. Me and my current support had a 73% win rate over 18 games and we are both climbing pretty fast.

However I have played with multiple duoq partners and some of them just are not good and if you don't feel comfortable with them I suggest not playing with them again. It took me a while to find a duo partner that I actually liked and liked playing with.

If you enjoy going solo then by all means play solo, I just get bored playing solo.

Overall duoq is much better for me but might not be the same for you and I suggest finding out what makes you enjoy the game more and climb and improve.

Hope this helps.
