As someone who has used partizans in base PSO2 for about 300 or so hours I really hate how they're bringing Volkraptor back in NGS. Here's my issue with partizans in base PSO2 that are also likely to happen in NGS as well.
Partizans live and die by their Volkraptor combos. By that I mean in order to do optimal damage with a Partizan you need Volkraptor which gets tedious when your entire optimal dps revolves around 1 skill.
Because partizans are almost balanced around solely Volkraptor their upfront dps is far weaker than swords but are more backended in damage. Sure partizans have slightly more dps than than swords overall but it's much harder to get that dps increase over swords which are much easier to use for very little downsides.
Even though Volkraptor is the main form of dps for partizans it's still very much bugged in that the projectile will often disappear or go straight through the enemy tanking your dps for no reason.
Volkraptor is just straight up boring and doesn't seem to change in NGS. It's not an interesting concept nor is it interesting to use.
In conclusion I think bringing back Volkraptor will be a huge mistake and a balancing mess. It really shouldn't have been added in NGS, they should remove it and replace it with something more interesting.
