This is my first Mobafire guide, I'm still learning how to use this website and I will be updating this guide in the next few weeks, hope it can help you in any way.
Also bad english. ~

If you're facing a bot lane/jungler with lots of CC (i.e. Varus, Leona, Fiddlesticks, Nautilus, Sejuani), you can also use Cleanse instead of Heal, works great.
Use this instead of Heal if your support decides to use Heal. Not recommended if you're not duoing.
