Well, some talents' description are way too simple to reflect their goal, sorry for that :) It generally just gives a range for the shuttle to pick the reaver. It's not global. The range, I imagine, would be not that large - like some healing spells Supports have. The inspiration come from Warp Prism change in SC2: Legacy of the Void expansion, where it gains a ranged unit load. Special mount is to allow Starchaser to do some other works, like scouting, exp soaking or even some offensive.

I guess that makes sense :) Something like 'circle' will sound more angel-ish.
