Please don’t interpret emphasis as shouting, it’s emphasis because you seem to be glossing over a lot of things.
You’re glossing over how utterly broken this is.
I doubt the devs would ever do anything quite this underhanded as to deliberately implement such a significant and obscure change secretly.
This has all the hallmarks of a bug.
That’s not an example at all, devs explicitly said how it was supposed to work.
They explicitly said how it should work and that it not working that is a bug.
And even if you didn’t know about that post, that’s not an “obscure mechanic” that would just be an inconsistency. It’s not actually that consistent what ults do or don’t allow you to continue to gain ult charge.
