You can use improvisation in E3 after having dodged the first charge. There's plenty of time for a few ticks.

Technically you could even use it on fights with short downtimes for a tick or two. It has niche use on Innocence when the boss jumps away doing his dash attack, if the Steps are on cooldown it is a damage increase to get those 1-2 ticks of Esprit. There are plenty of similar, less than obvious niche uses for the skill.

OP: I think the skill is fine for a downtime filler. You're basically asking for a rework for the purpose the skill exists for at the moment.
Unless you get at least 10 espirit throughout the fight with Improv it is not worthwhile to use, before adds in E1 is good if all members are stacked with you(df almost never), E3 as well would require entire party on you to get those quick ticks to get that 10 espirit minimum
