Guided doesn’t need ar, neither does fury on swap, just strafe and multi but even in those cases you’ll have a bunch of ar from skills and fanaticism. The only thing the ar might help with is high def chars like smiters but smiters are pretty much a hard counter anyways.
Zons also use life really well because of dodge skills, bo, mb and max dr. Any health they get turns into a bunch of effective health.
