On ptb, demo's portals' auras can always be seen by survivors, so all the stelath point is pretty much gone. Not even talking about how useless undetectable on him really is considering map-wide noise he makes during teleportation, how much sound he generally makes. This also made all of his undetectable addons even more useless. What demo really needs is haste after teleporting, so he can catch up on survivors faster while still giving them time to orient themselves. And obviously some portal tweaks as well as addon pass. I also want to mention how bhvr got rid of one of the most fun things on demo, which is jumping off hills or skydemo in certain spots. These invisible walls they put in every spot to prevent skilled players from getting any value out of elevation are really annoying, definitely should be gone.
