Supposedly one on one is when you have to use auto attack or eye but ayla is so damn expensive...

Yes one on one really isn't her thing.

Yeah, rage is very good against teams that stick together, thats why i waited to attacked them when they were together. In this video i surprise them but i have a feeling that she is a bit squishy to be a brawler, especially early game

Well she does take less damage depending on the amount of enemies around her, that was just to stop her dying all the time. You should play around her skill if you're against her.
