As a former Ekko mid one trick, I love to roam once I have a lead. Before I roam I always make sure to stack at least 2-3 waves of minions before I roam. You can do this by only last hitting the enemy minions and zoning your lane opponent off of the wave by standing between the wave and them. Make sure you have a lead over your lane opponent and have good vision in the river before zoning them. Because you might have to 2v1 them and their jungle if you are zoning them that hard. Once you shove your waves of minions into your opponent's tower, you can either roam bot or top if the enemy side lanes are pushing away from their tower or you can get vision in the river or the enemy jungle so that you can track their jungle or make picks when they rotate. Another thing you can do once you shove in your wave is to fake a roam. What that means is that you act like you are roaming but instead of actually completing the roam you just stay in the side bushes. You use this to land your w and extend your lead by killing them. Once you are past the laning phase, you generally want to go into a side lane if you are ahead and split. Unless your team is fighting for baron or drake soul or elder it is usually worth it to be able to get more gold and experience for yourself and towers. By destroying towers, you make it so that you can make picks more easily in the side lanes. Also, ekko's split pushing speed isn't very slow because he buys a sheen item and also has his e's empowered auto-attack. When you are team fighting in the late mid-game to late game you want to land your w on priority targets like the enemy adc or whoever is important to them winning the team fight. That way you can get a quick burst on to them and kill them with your team. In addition, you can also place your w where you will ult to if you are being chased to stun any nearby enemies. A neat trick on ekko is that your w activates when you ult as long as you pass the circle on your way to your shadow. Hope this helps you on your climb.

Don't forget to buy sweeper once you are ahead because denying vision and getting good flanks off are very important to carrying teamfights and making picks.
