D/D suffers because any changes to D/x and x/D will affect P/D, S/D and D/P. There’s no other way to improve D/D other than tweaking DB, which is the only skill with no connection to other weapon sets.
DB is a horrible skill because it suffers from slight game lag and bad pre-cast and after-cast delays. So even though they improved this skill without addressing its clunkiness, D/D will remain inferior to other weapon sets.
S/D rarely makes use of the dagger, P/D were able, or still can adjust their traits to make a lot of stuff work as condi builds are a bit easier to set up. I expect them both to use DD which will be a huge buff to them both. Still as it is now a buff to X/D wouldn’t really buff S/D nor P/D.
Like I said a lot of times: I like Death Blossom as it is and it is useful to me – sure it’s the only “D/D skill” but I don’t think you can put everything D/D is lacking into it and then everything would be fine.
My suggestion is to redesign the Dual-Wielding feature that when you equip similar weapon on both hands, it doesn’t just change your skill #3 but all 5 skills. This way, changes to D/D will have no connection to D/x and x/D because the whole D/D weapon set is isolated (by extension, same with P/P).
Unless they take this approach, there’s not a lot of room for them to make any changes because they have limited themselves with this kind of weapon set design. So the first step it to open up the weapon set by allowing them to explore other solutions. By changing all 5 skills, the D/D auto-attack will be different from D/x auto attack, which means that D/P can alos be balanced (or nerfed) without affecting D/D.
The problem we’re seeing right now is that D/D needs a buff but D/P and S/D needs a nerf. Nerfing D/P and S/D kills D/D. You can’t buff D/D without making D/P and S/D over powered. So there’s really only one logical solution, separate the skills for each weapon set. The same approach needs to happen with P/P. When Black Powder was nerfed because of D/P…P/P became kitten if it was not already. And this will just continue until they made the change I’ve suggested, there’s really no other way.
With that you’re kind of right (except that no thief weaponset needs a nerf right now – with DD that might be a different secnario, but it’s not in game yet), my point above still stands though. How about a trait “If you wield 2 weapons of the same kind, then you’ll get this buff” if CnD were changed to blind then CiS would be “free”, although then I probably really wouldn’t bother to take that line as it tries to make me into a saint “you rez faster, you heal your allies” wheras I have once been a proud “warrior”.
