I made it to gold without really trying

So uh, some of you may have read my previous post where i raged about being stuck with idiots. I still maintain that. But I gave up on playing the jg role. And I went from s4 to g5 in a week. The only change i did was play top lane. Seriously thats it. I played jax mostly, when he was banned I played nasus. all i did was splitpush the entire game every game and I won. I can't even make this up that's literally all i did. I did have a tough time against the inting sion build. But if my team didnt ff at 20 minutes i was able to outscale him with botrk and guinsoos. So yeah. I made it to gold without changing my champion pool or playstyle. Just weent from jg to top. Im trying to get gold in flex as an adc only and Im at s3 78 lp.
