It's in the recent patch notes, but I didn't notice it until playing for hours: The only thing Chameleon does now is give you 25% cloak energy when your shield pops, which makes it nearly useless. Go to your loadouts and change it to something else. This isn't a complaint, just a PSA. The change is probably for the better as I know I've been able to get away with some truly ridiculous tactics using the old Chameleon. Though it'd be nice if they replaced the benefit they removed with something more reasonable. Maybe increasing that 25% to something higher, or remove the energy drain from cloak for a few seconds?
