Yes, builds are always going to have a ‘big hit’ that you want to be boosted as high as possible. But the method of boosting doesn’t have to be boring on its own. You can, for example, have other attack skills apply the debuffs.

This is what some of the other D4 classes do. It’s also how I’ve built my class where Meteor is a very high damage method of applying immobilize which grants me extra crit damage and I then hit with charged bolts.

Ideally your ‘boosting’ skills are effective at clearing out trash and you only really need the full boost stack on elites.
