Honestly there's a whole lot of stuff in this new patch that's fucked.

• Pip system is hell, seems impossible to rank up without a perfect game. They change the ranking to be much harder, but STILL they aren't taking into account perks/items in rank, which seems like an obvious change.
• "Optimisation" for PS4 seems to have been "turn graphics to potato", substantial loss of quality and resolution is sub 1080p now. I genuinely thought something was wrong with my console at first.
• New matchmaking is pretty fuckin awful too, slightly quicker to get a match but RIP green ping. Still getting really wonky matches with very dissimilar ranks too.
• Loads of extra new bugs added, most notably with audio, but I'm sure there's more.

There's discussion to be had over the changed perks too (not just DS, a good number of things were reworked) but I'll leave that to more experienced players. I didn't buy the new DLC so I can't comment on whether the new characters are any good or not.

Short version is that the game really doesn't feel fun to play right now. It seems like they didn't test these changes anything like enough before rolling them out.
