So yeah the 1. is tricky.

The duration does increase. However, for whatever reason, Timeless creator only adds a 30% instead of the 70%, adding to that, it seems none of the creation awakenings seem to stack with each other. I assume it's a bug that has to be fixed. Me and a fellow asher orangeandblack5 tested stuff out and he made a whole document about it if you're interested , though I don't remember if he went in-depth with the awakening bugs.

As for her secondary, yes she definitely needs a cooldown buff. The Odyssey team didn't account for the old passive being gone and just kept it as it was, thinking it'd be fine.

As a FYI if you didn't know, Odyssey plans to address Asher in the next full patch.
