@mnemoidian: no idea about "THE" building site, outside of the raids and the sorties there is no real need to go super sayan on builds.
For guns its quite simple, if you have a crit weapon you go with crit, if not just one element build and be done with it.
For secondaries, seems that the akstilleto power creep is real otherwise, spira prime are the throwables of choice I think and vaykor marelok still reigns supreme.
Shotguns got buffed with vaykor hek and the sancti trigris being the best options. vaykor hek can be modded for crit from what I understand, but I like the tigris more.
Status seems to be regarded as eh with some small exceptions.
Melee right now is the question: can you berzerker? if so you you basically do this:
Single handed daggers right now are mostly covert lethality builds. Covert Lethality is a dagger only mod granting fatal damage on executions, so you can backstab anything regardless of level if you can trigger the back stab animation (stuns, sleep effects work as well)
@dudeglove: Scales now with some of your secondary weapon mods, they did lower the base Damage because of that. I haven't done a lot of testing with it tbh. So no idea how much of a buff/nerf/nothing changed it actually is
