Rapidfire Canon Ekko

So I been thinking RFC would be great as the first items on Ekko. Here is why. The states gain help with the reliability of his skills, cause lets face it, his skills are very unreliable.

What you really want from RFC is the movepeed, attackspeed and the range extension on his e. The crit is nice but not really what he wants. Now here is how this help Ekko

The move speed and range helps to get a huge blink to target. This means he has a better chance of dodging skill shots with the first dash and landing his E. The extra range also helps blinking through skillshots. The movespeed and attackspeed helps to get the second passive stack off much better. Then lastly, you can land your third passive with you q, slowing them down so you can accurately cast your w and continue to get auto attacks in. The attackspeed also helps with his w passive.

I've tried it and it seems good. Only draw back is no ap but you do get magic damage from the RFC passive. So magic pen rune recommended along with thunderlord as Ekko E counts as 2 stacks of Thunderlord.

Continue to build and and he gets insane movespeed and burst.

What you guys think?
