Also, when your support go in for a little poke (like an AA), don't go ham. I just wanted them to back off a little bit so you can cs. I play a ton of Thresh and AA's hurt early game. If I land a hook doesn't mean go ham all the time. Usually it's for the scare factor/ zoning. It's not always about the kills.
I'm picking up Nami, and I've noticed that adcs tend to over extend when a bubble lands. Just AA them a few times or maybe use a skill for more damage if you please, then go back to farming.
There isn't a need to use your escape tools to engage, use them to re position or escape.
One last thing, help your support ward, we can only ward so much and try to cover as much as the map possible. If your going to farm without vision don't blame me when you get caught.
