Chop sustain or damage for weaver. Chop self support, control, or damage for firebrand. Weaver has endless evades and does tons of quickly applied damage, sounds like a condi thief. Firebrand can carry themselves through outnumbered situations, and even if specs for sides, dueling they can still provide better support than the other options. I see 3-4 weavers in most of my games. No one is not playing guardian, but firebrands are the most prevalent. A game without and ele or a guard x 2 across teams does not exist in today's pvp. Pistol whip thief is super prevalent in thief, but these are just as frequently in games and come with the same damage output and sustain. Weavers are quite mobile too.
