Once that haste burst runs out, fighters get behind barbs in the DPS line. I would rather have 30 minutes of sustainable DPS than some 20 second party poppers that last ~ 7 minutes.
"Those of us who understand the nature of the game" would rather have the "20 second party poppers".
Running out of boosts isn't exactly common, and being out of boosts long enough for barbs to catch up is very rare.
