I gotta be honest i've no idea what the point of this thread is. But it reeks of elitist commentary.
I don't know really jack all about what awaits us in EP 5 and 6 but from my off time googling stuff about the game anyone that's dumping that much meseta into nemi/raven weapons right now are in for a rude awakening come those episodes. Nemi/raven won't be worthless but they won't be anywhere close to BiS with the upgrade paths i've barely read into.
Nemi/Raven was given to us early so we had something to float us for awhile while content kept getting jammed out. It's not like they're the best bar none atm. We just have fewer options to play with. Anyone can take a gix or sigma on a budget and do just fine so long as they've specced their build properly and grind that stuff to max.
Far as i've heard about the successor classes go they're pretty powerful on their own and brain dead easy to play. So if someone's doing bad as the class they likely just don't know what they're doing. Nothing to do with the gear itself.
