I've included some simple pictures to kind of give you guys an idea of how Echo's abilities would work. Echo is a bursty assassin, really relying on his ultimate to melt single targets. He has some slight CC in his E which can provide a good engage for his team as well as a good disengage for himself. His dash applies on hit effects as well, meaning he can apply slows or debuffs to enemies that he dashes through. This also helps out in the jungle, due to each part of the dash dealing damage, allowing for decent clear speeds.

So let me know what you guys think! Give me feedback, whether it be positive or negative, and I will gladly accept your critiques and try to improve Echo and future champion concepts! Thanks guys!
