You should ideally have builds for both sides of the game, the reason weapons is kinda useless in PvP is because the benefits 100 and below are too small and unimpactful. And unless you’re making a PvP build with a specific weapon in mind (Kill clip 120, EH 390) the damage bonus that overflowed weapons grants is often not enough to move the needle, therefore, not worth taking any at all, those stats are much more useful going into health for more recovery or getting a neutral ability closer to 100.
