I think Nasus, Yorick, Gangplank, and Xin can work bot lane in place of a carry

You would pick these guys to open up other picks for your team. Going to test this in a bit.

Each of them would serve a different purpose and can lane safely to an extent:

Nasus: You would be maxing E and constantly keeping your tower safe with thr E waveclear whenever pushed in. Never try to push or you overextend. If you get dove you can E, W, and at 6 ult yourself. You would be the wall of bot lane to protect your turret. Non exsistent kill pressure.

Yorick: Similar to Nasus in being a wall in lane, you need to not push and focus on farming and sustaining with your Q at all times. Your Ghouls help defend very well and it is very easy to bait dives provided you arent low to begin with. Once you hit 6 you can provide global pressure by going to a lane that your team is going to push and dropping maiden there. Or you can use Maiden for fast objective secures such as Dragon, Rift Herald, and Turrets. No true kill pressure.

Gangplank: Similar to lane GP just bot lane instead. You want to farm and not get poked down too hard. You are a bad idea to dive and once you get sheen you can start waveclearing with barrels. Plays like a farm adc.

Xin Zhao: Plays like a carry but must be passive until 3. Once he is 3 he can make plays but only with the support and if he isnt over extended. Can snowball really hard and go back to farming under tower with his heal if behind.
