Bleed spec
DD spec is better dps for sure but what bleeds let you do is use stealth to the fullest. You can apply constant ranged pressure while remaining in stealth if you want. The decision to leave stealth early and increase pressure or remain in it and heal and allow CD’s to come back up is the sort of stuff you do while doing the P/D stealth dance.
The main advantage of P/D and bleeds in general is allowing you to take on many bad players and glass cannons at once and win, given enough time. It’s really fun. 1 on 1 vs good players and bunkers is still fun too but it will take a long time to kill them.
