As they are now on test they are pretty much unusable at it intended task. At least leave the old version available.
New Ql 200 version adds + 65 on perception and conceal (was 400 conceal and 65 perception). So it actually does nothing at all. Except you are able to fight with the hud on. This is a nerf, not an improvement.
Additionally; non-adv's in perception-setup is nerfed (since stareline is gone/become a selbuff) and the cloaking device got nerfed (the current one on test is indeed useless cause it doesn't do anything vs the excisting perception-values) which it was no reason for doing. It was a great system where perception-setup players could enforce sneakers (shades and agent mainly) to sacrifice a hudslot for wearing the device which added 400 perception. Those values (and stare) on the device could have stayed while enabling combat/casting aswell. It would still be a consequence to wearing it. So gone are diverse setups and swapping stuff. Sad when ao is about customization.
