Once I was fully maxed gear (aside from extremes) I haven't had an issue where I couldn't maintain enmity. Dropping Grit for boss fights is also possible but I usually have to do it after a couple dark art's power slashes (will usually leave people at like a 10% enmity difference). There's definitely a massive difference but it is doable. Except with Samurais, I hate grouping with them because their enmity is always stupidly high.

It's not great but doable.
