A champion design challenge for riot or anyone interested

The Challenge: Design a champion concept. Can be an idea, with a couple moves, or a full kit. Make it engaging, interesting, and unique mechanics are encouraged.

The restrictions:

-The champion must exert the majority of their power budget in melee range and use melee auto-attacks 100% of the time.

-The champion must be designed with solo-laning as a strong option (so they need an answer to ranged harass)

-The champion MAY NOT feature any DASH, BLINK OR JUMP. ONE speed boost is allowed, if on a basic move it may be up to a Garen/Volibear level, if on an ult it may be Rammus Powerball level, but the champion must maintain full character control during the speed boost.

I would really love to get CertainlyT in on this, as he was the last champ designer to attempt the creation of a new immobile melee champ....THREE YEARS AGO. Since 2013, there have been twice as many ranged champion releases as melee, and every single melee release has used an instant dash as a major feature of their gameplay pattern. I'm curious whether the folks at riot think it's possible to change, and I hope that a thread full of ideas may help.
