Not too excited by those changes, but they won't hurt my characters. Just seems...unnecessary to change the Bladesong, to me.
It doesn't really make the sticky EK a thing of the past. You can just use the old version, for one thing. For another, the EK can still take an entire attack action adn then BB with a bonus action, so the warcaster part isn't that important. Just take a Sentinel instead.
I really strongly dislike them changing the class in a way that hurts melee focused Bladesingers. That's the point of the subclass. Luckily my group where I play a Bladesinger doesn't have long adventuring days, so I'm unlikely to run out of uses if we switch to the new version.
