Well maybe your strategy is good. I already see that in game (and with a premade), and it was a fail. But well, maybe my team was a bit bad.
And I agree with you about Solo Ranked. But there are some really good game with awesome teamplay. But sometimes you are with the bad team...
By the way, my favourite champion is Sivir (but my main is Ashe).
I did a ranked game today, they had a jungler, not us. So me as Ashe with Janna vs the solo lane Morgana. Zonning
. We outlevel her. It was funny.
