Tips for beginner Mids?

annie is the good option for it; Try to play with her

Try to limit your champion pool and learn more about the role. Be aware of what is happening near crab and sidelines in order to rotate and help if needed or gank. Also, i would recommend looking into wave control; I do believe it is game changer lol

try xin zhao with kraken slayer and ravenous hydra, thats all you need

ALWAYS PING MISSING MID WHEN YOUU DONT SEE YOUR LANER. OR ELSE YOU U WILL GET FLAMED 100 TIMES.

learn to control a wave in the mid this is very important to not take too many ganks, since it is a very vulnerable lane

Stick to one champion in the beginning. Then watch combo tutorials on how to kill a champion. I struggled so hard in the beginning to try to do that. Also the updated item sheets are a little easier to follow.

aim on having good farm and not to feed to have a good impact in lategame

Remenber to manage your wave properly, no extra pushing in early

On begin start with mages, like Lux, Veigar, Annie, Malzahar

focus on watching your map and being cautious of ganks. And if laners or enemy junglers are out of POS and you have your lane pushed in, think about supporting your team in a fight. Overall improving your last-hitting on minions is the first thing to learn tho
