I foolishly started my prelims in duo queue and went 1-5 before attempting solo and winning most of those
Duo queue isn't bad, especially if your duo partner is any good. I'm guessing you didn't enjoy the experience of duo'ing with a Bronze V. Also, you were playing with Silvers most of the time which is how you got Silver status
Tip: Don't get Rylai's Crystal Sceptar at all on Ahri. Especially not early game... Maybe as a 6th item... It's not very cost efficient, especially if you're behind. The 3 items you got that build into it would've been a lot better spent on Void Staff instead. Like the Giant's Belt and Blasting Wand, 1800 gold, would've been better spent on Large Vod. vs a Lux, Chalice then working toward deathcap is also a good choice to go. I recently had an Ahri in my ranked match that got Rylai's as second item and it did not go well at all.
