Neon changes to her slide after patch 9.02 [before 9.02 you could get a free slide if you used it just before the round started but now it consumes it even if it's a bit delayed (notice the slide bar in the clip)]

This is correct, this is legitimately my bad (just forgot to add the bugfix to the patch notes). Neon getting 3 potential slides a round is pretty crazy at a baseline (2x slide + ult refresh, even before kill resets) but we fixed some impactful balance-impacting bugs that had always been around while looking into making the Neon changes and some of them had to go out a bit later than 8.11 for QA/testing/engineering review etc

Neon can sprint and slide unlimitedly during the pre-round because:

• it's enjoyable to fidget with
• also the slide is also a somewhat difficult learning process on the inputs side, so being able to practice it during low-stakes pre-round is nice

Chamber we've discussed removing his free verticality TPs from in the past, but opted not to given:

• free-pre-round boosting is usually done to defensively posture on angles, (especially with a sniper rifle) which we view as a part of Chamber's defensive profile.

• Also, given that Rendezvous has a cooldown it would be extra punishing if you were late on his pre-round chores or setups and potentially cost him his signature ability, which is particularly painful given he wants to have it for combat in early round barrier-drop fights.

I'll get on adding it to the next patch notes on Monday, would be in 9.04 notes most likely.
