Make subs unable to traverse station turf/tiles

[KikiMofo]

Here's my proposal:

Subs move on plating at regular speed, but the soft fragile floor tiles of the station crack and jam up the treads for a moment, probably represented via a 1s action bar to break the tiles and make them plating.

This retains a sub's advantage for area control, while nerfing their unimpeded juggernaut qualities.
Thoughts?
