Off Meta picks. Do not doubt them
Story time.
In season 4 me and my friend both finished our ranked games I was placed in Bronze 4 and him in Bronze 5 (Bronze noob you dont know anything) yeah yeah anyways. me and my friend pretty much only played ranked games whenever we were on and only with each other.
We would duo Vel'Koz (Me) and Volibear (Him) bottom lane. needless to say almost every single pregame lobby we were raged at and called trolls. But regardless we would do this almost about 95% of games. The synergy of those to champions worked so well it was almost mind blowing. Voli has a really strong early game/mid game. which definitely caught people off guard (passive op). Volibears biggest downfall though is that any crowd control makes him almost useless. Well when you play bottom lane where more than half the time the supports come to you. Leona,Thresh,Blitz. (those were the most popular at the time) you make volibears life way easier. when Volibear would dive or get engaged on by their support he would just run pass the support and engage the adc (if they were in range, if not just go for the support) and toss them back to me where I could just full combo them and earn an easy kill.
we won our lane around 80% of the time and we had an 78% game win average whit this duo. by the end of the season me and my buddy had both successfully climbed out of bronze and into silver.
never doubt the strength of an off meta pick. and please share your stories of off meta picks if you have them!
and
top lane. I have had a really good run with them because people simply don't know how to go against those two in top lane when they are building damage and not support.
