Second Wind is a terrible ability and either needs redesigned or outright removed.

its crazy how resistant to change people are. for Second Wind of all things.

where was this energy when the devs took Bard, Scholar and Astrologian behind the shed and lobotomised them with a shotgun in Shadowbringers?

There's a difference.

In this situation, people are merely suggesting a change, and people are resisting it before it reaches the devs.
In those situations you described, the devs just took those classes behind the shed, lobotomized them without concern or being properly informed and then just showed up like "damage is done, enjoy your oversimplified job".

On the first case, people can still prevent that. On the second, people had to deal with it and anyone who wasn't okay with it was just being "too negative™" and a nasty contrarian.
