I guess it comes down to how you define "master builder". If it's all about the stats, then I doubt there are many up-to-date videos, if any at all.Do they have?
I'd love to watch a vid or two , post qf.
I just build qubes of puke.
Going to double down on this, since post-QF maks things FAR easier to aestheticly build with. If OP is looking for more "most effectic tactic available" (META) then they should just open the config files and do some math. KISS of META is "Weapons are always more efficient by mass and energy and volume than defense" as long as you can land your shots anyways.I guess it comes down to how you define "master builder". If it's all about the stats, then I doubt there are many up-to-date videos, if any at all.
If on the other hand your definition is about aesthetics, then I don't think "post-qf" matters at all, and there are a couple of really talented builders, some active, some long gone but still well worth watching.
