What it needs now is a grapple/hook that comes from the upper Khaydarin crystal and orientated onto the grid.
I've been following this page for some time, and I have to say now that you're doing a great job with improving the SC1-to-SC2 model assets.
HOTS has added new mechanics and gameplay changes that are a must for the Starcraft II melee.
If you wish to create an arcade type map, you may only use WoL as dependency as long as you don't need the ones from HOTS.
For maps like Fastest Map Possible, which are about extreme (and fun) melee gameplay, there should be two versions: one for WoL ( which already exists ) and one for HOTS, because it will improve its gameplay/graphics/mechanics + add the new units.
