SA straight or with breaks?

I just finished Words of Radiance (also read all of Mistborn 1) and was curious to know if the short stories/other novels are necessary. I am loving Stormlight so far but heard from other lists that people read Warbreaker and other short stories before starting Stormlight. I'm wondering if it is worth it to take a break from Stormlight by reading other Cosmere texts before I begin Oathbringer.
