Didn't know multi-weapon was nerf'd on launch. I was asking around looking for ideas to make weapon combos. I initially wanted to make each melee weapon to pair with a range/tech weapon to deal with flying mobs and ADHD bosses. All of the idea quickly evaporated when I found out that fused weapon no longer use base weapon's damage type like CBT was. With how few the augment capsules variety are currently in game, it turned multi-weapons that are not of the same damage type into more of a waste of resources.
I'm not talking about combos like the rifle/launcher, and the two are all range damage anyway. Even with compatible combo like this, there is still obstacle to prevent players from building their own diversity. Out of the current five 4 star weapon series, there is only Resurgir series that can make this combo possible. (yes not even gigantix's Straga series have all weapons) At this point, I cannot help but to call the one responsible an idiot for making such stupid decision of making weapon types dependent on weapon series.
During CBT I made the suggestion of letting different series be multi-weapon-able because the two 3 star weapon series Trois De and Theseus each cover only selected types. The fact that base pso2 has been providing us with a variety of different series that includes ALL weapon types makes me more and more frustrated that I have to deal with incomplete weapon series in NGS. The series only limitation on top of multi-weapon's damage type separation between base and fused are really making this entire function seem pointless and wasteful in reality.
The only good benefit at current state is simply just to fuse main class' weapons together (ie. knuckles/daggers) to save meseta, minerals, and capsules on upgrades.
