A 1224225223122242 would still allow you to focus on the fight because it's not mandatory to fulfill your primary role.
Saying "please keep the 11111 because anything else would stress me out" is nothing but egoistic because not wanting to improve healer downtime options means purposely gimping the skill ceiling just so some people can feel comfortable with their easy mode and everyone that has grown out of their fluffy little baby shoes has to be bored out of their minds or hope for clown fiesta.
You can clear every DF content without ever touching a single dps button, you can clear the first floors on Savage with way below optimal healer dps contribution first week. If you need to focus more on the fights, set your priorities correctly and focus on the fight by simplifying dps for the time being and as you get more practice, you'll naturally get better and eventually use the full kit. That's how the other two roles work as well.
Every class has to deal with not being able to play their class to its fullest potential when learning fights -- except healers, better give them a skill ceiling low enough for ants to bump their heads.

This mindset is exactly the reason why an entire role has grown stale: better keep the skill floor as low as humanly possible so everyone can feel happy and comfortable smashing one button over and over.
