I did this with Sona while the nexus was open. Lich Bane and a ton of other AP. While both teams were dancing at Baron, I just floated in and powerchorded the nexus to death. My own team didn't even know what happened.
Backdooring is such a filthy way to play in my opinion. I can understand if it's out of desperation but when it's constant backdooring and running off after killing the inhibitor I just wanna smack you :Y
i don't get it lol
Yes

Once my teammate tried it. We won but only because me and the other 3 were able to stop their recalls at dragon.
I'm not sure if that cat is lucky or scared...
