Here's how it pans out:
I'm using Raynor's Grenade ability as a dummy for the player to use to select where they want to jump to. A validator for the effect prevents you from jumping up cliffs or on ramps, but you can jump down them or across flat terrain. The jump looks...fine visually but the unit that jumps simply gets frozen right after they land. You can still queue orders, target abilities and whatnot, but the unit will not do anything at all.
Note: The ability doesn't have to be Raynor's grenade, but just for the sake for simplicity I used it instead. Mind the messiness of the triggers.
Although it seems to be I'm not too sure if it's MUI as well.
Basically, I've altered a few things around with SCMapper's Simple Leap (http://www.sc2mapster.com/assets/simple-leap-function/) to make a jump ability.
