I'll keep this brief for you. You are a *****, their *****. Allow them to make you their ***** juuuuust until you get that 1 gank. They will shove you, and they will try to poke you, if not take it and have a peaceful lane with some E harass and plenty of farm.

Your farm under tower is terrible, and when they realize that they shove you in and don't stop shoving you in which makes you a perfectly gankable lane. Ideally, getting camped on middlesticks is what you want, but obviously that's not going to happen most games you play, let alone all of them. Regardless, scare them off with your E and try to get as much farm as you can before they realize your champ is dog****.

When getting ganked the best combo is to E from range, get the silence, and get in close for an auto. You proc glacial and when you feel they're about to flash that's when you Q, it's all intuition at that point but still pretty simple.

ROAMING

Roaming is a difficult thing with this rune setup and build, since you're not running predator, you lose the ability to gank an un-shoved wave, and since your team is probably blind, everything is likely warded. I prefer to stay in my own lane for a bit, help jungle if they need help on scuttle, and definitely fight dragon when you get 6. From there you wait until everyone starts grouping and you take jungle camps and let your AD farm, you should have your 2 items so you're basically set.

PLEASE BE UNPREDICTABLE

The second the enemy team forgets about you is the second you just come out and rail all 5 champs at the same time. Make sure you're aware of their vision placement and learn their ward habits. Don't forget that you can also drop your sweeper and ult while the ward is being swept because they can't see you. Those are just a few general tips, you'll get the hang of it.

When you make plays, or outheal a mid laners burst and your team sees, they realize they can trust you. You need to drill that into their heads because without your team, you champion is pretty useless. Use your chat, tell them "have a little faith boys" every now and then; It works, trust me.
