I hear this a lot from people who can't math and don't realize just how strong their melee was before CO got destroyed.
CO now stacks with Pressure Point. Not AFTER Pressure Point, with. To make things even worse, CO no longer stacks with itself so the damage increase is linear. Instead of being the savior of status weapons, it is now a situationally better PPP.
The following math is how much of a damage increase Primed Pressure Point is in a build that also contains Condition Overload:
0 procs: PPP is 2.65x increase
1 proc: PPP is a 1.75x DPS increase
2 procs: PPP is a 1.485x DPS increase
3 procs: PPP is a 1.359x DPS increase
4 procs: 1.285x
5 procs: 1.236x
5 procs: 1.201x
...
11 procs 1.116x
12 procs: 1.107x
13 procs: 1.099x
14 procs: 1.093x
15 procs: 1.087x
16 procs: 1.081x
As you can see, by the time you get 3 or so procs on a target, PPP is no longer worth the slot. It still adds damage, but other mods (say, an elemental) add more. You don't run PPP and CO in the same build for the same reason you don't run Serration with Chroma, and why Hornet Strike is more and more optional on Mesa's Regulators the higher her strength goes.
Now, PPP is a good mod. A replacement for it on status weapons can't be *bad*, but compared to what it was CO is dead. Crit melee is almost universally better than status melee now. Status can still scale a little better at high levels, but for the levels most people will see (say, under 150, possibly higher) crit is simply better.
So, your staff zaw may seem fine, but it doesn't scale nearly as well as it used to and its top damage is way lower. My status zaws are noticeably worse feeling and some of my crit zaws were also hit hard.
For example, I had a crit dokrahm that I used with a hybrid build (basically a crit build with one less element and CO) for ESO Saryn. This build now feels way less powerful. It still kills stuff, but not as fast or hard as before. I dropped CO for another element and it feels a little better, but it still is not what it was.
