There are no magna grids where you run 4+ barred grand weapons. In fact, a majority people will have 1 0star weapon for their grids. The ones that can be run in magna (PNS series + LoF) have 80% of their value unbarred. Also, they aren’t run because they’re strong even when not boosted; they’re run because the don’t have primal modifiers at all (with exception to LoF).

The addition of the PNS series etc. is honestly never something I have had a problem with. I’ve never viewed it as a bad thing that magna can now take advantage of powerful grand weapons. A lot of people say it makes magna less f2p but like.. no one is making you roll for them.

I disagree with modern SSR characters being bad. Most of them have very usable even outright strong kits. There’s pretty decent flexibility with the character checks of endgame raids. Nothing compares to Faa HL on release in terms of hard character checks. And that was for a grid piece more important than anything in Revans.
