Crouch walking is much less visible than Live
Standing is less visible than Live
Running is slightly less visible than Live
Sprinting, no change
Basically we added proper tiers of visibility based on movement. On Live there is three states deepcloak/poorly cloaked/not cloaked; on test there are 5 states deepcloak/quasi deepcloak/cloaked/poorly cloaked/not cloaked
Edit: We are also working on fixing the bug that can prevent attachments from going into deep cloak
