I'm not a massive fan of the way they have been introduced. I would have much preferred a 3rd slot was opened up on each class; and that is what held the passive perks. Also some are clearly bonkers right now - but that's a balancing issue not a design one.tbh
I am not all aposed passive perks.
Some of the money perks for example can be interesting when they are high risk and high reward.
But overall I am not happy with how they were implemented.
If you add 3 new perks to add variety in gameplay but one of them is so good that you just need to have it that's just bad gamedesign.
Also as I said before perks are indistinguishable which is my personal biggest gripe with the last patch.
