With the recent change of the bow from bleed to poison damage (meaning less PvP damage because poison damage is reduced by armour), I don't think there's any BRP weapon worth using in their current state.

All the other arenas have really powerful weapons that are still used often (DSA = bow, dw and VMA = bow, inferno destro). However, I don't see any BRP weapons coming even close to them. ZOS should buff them to make them at least somewhat exciting. In their current state the BRP weapons have about the same power level as the Summerset PTS Cloudrest sets (aka really useless).
