There are other viable DPS war builds, they just take more effort to execute. They’re also generally better overall for a team because they’re not nearly as reliant on having at least two CDs up to do damage.
Also, 100B is easy to counter. Most 100B wars will start the bulls rush outside of melee range. The animation start is very noticeable. Just dodge. If, for some reason the bulls charge lands, pop a CC breaker (preferably with stability) and dodge away. Congrats, you only took 2-3k damage at most.
