It is so ,so ,so ,so important that you WILL engage with your W/Parallel Convergence. It gives you a huge edge ,MUCH more than you think. It grants you more ability power on your basic attack and if your enemy is within the radius when you activate it (walk into it.) it will stun them and you will get a huge start. If the champion you're facing is smart and sees the animation when ekko casts his W and avoids it ,place it behind them and chase them into it. Ekko ,in my opinion is only vulnerable early game. Its so easy to lock down your enemy champion with ekko if played correctly.

If you get ganked ,made a stupid ,greedy tower dive ,or got caught baroning/dragoning and the other team is tailing you ,its not over! Your R/Chronobreak is so useful in these situations. The combo you should use is |

Step 1: W/Parallel Convergence (time it so the other team walks in it)
Step 2: E/Phase Dive (unless your ekko's shadow is already upon them)
Step 3: Penta Kill or unfortunate death :)
