we used to have a movement skill on weapon component, this got removed/moved/changed with the release of FG to place them on medal augs (universally unused)
i’m not against more movement options (even if i stopped using 4+ movent skills myself now despite using them before), components could be a universal option.
Part of the issue with adding to existing skill, you’re changing existing skills, and it’s gonna impact things differently for different people and not be a net benefit to all. Two easy examples of that is 1-3-6, “these have bad scenarios”, if you’re disengaging on thermite mines, you’re detracting from every melee or facetank build ever that needs RR. Likewise reducing utilization potential for an absorb buff by not using it to push through (besides potentially breaking the distance and cancelling it i suppose).
So it has to be done very carefully if it all like that, and it might be simpler to just add the option elsewhere, than changing something that either might cross conflict with builds or simply change what people are used to with an existing skill Movement skills, can we get more - #13 by Gnomish_Inquisition. (besides OFF, screw that thing, turn it into a teleport 
)
There will always be build disparity in some way or another, probably can’t really be helped in some simple fashion.
