You go in blind, you get a mage and no matter what you do, if the enemy team is half competent, they steam roll the mages even if you have an adc that just tickles them.
What is your strategy? I can't seem to beat them. I just got beat by a full tank LUX because our team lacked damage somehow even though we itemized against her and some off tank Yone. And these are off-meta. The meta ones are even harder to beat.
Lots of good suggestions here. I personally like building BotRK, sometimes even on champions it normally doesn't make sense on (like tanks). The percentage damage is incredibly useful, and it doesn't always make sense to build AP %-burn items.
Yeah, I've even tried ad TF with Bork and felt like I couldn't even get the two tanks under half health before they ran over my team. And mind you, I even had a Nami with me! Lol I felt so useless
