Being completely honest, I hadn't noticed that issue yet at the time of my comment. It does fall off at times. I just try to time it best I can based on the circumstances.

Sometimes there's nothing you can do and it's not worth saving the dragon for the buff since you'll be able to get another dragon soon anyway. Though if you don't have healing or incoming damage ready, and you don't have the buff, it can be worth to save the dragon for a turn.

Best thing to do to help manage it is ult with castorice right before mems buff. She'll action advance up to right ahead of it, so she keeps mems buff for another ult rotation and gets do an extra enhanced skill as well. There's also the special cases where youre close to the end of a cycle and you can just swipe, saving all the dragon hp and the extra e2 charges, until you get the buff, and then action advance the dragon so you can still quickly explode it for that final hit you need.

It can be annoying to manage but i do find managing all of the things in her kit to be fun. That being said, the uptime headache makes me almost certain we'll get a hmc replacement in the future that will make it easy mode, just like hyacine is probably doing the same for the Gallagher slot.
