None DPS credit
For point capture/defense events, I don’t think it matters because you simply have to be in the area. For boss fights, they might make it so that it is based on continuous time in combat proximate to the event, contribution to healing, contribution to break bar, etc. It’s kind of hard for me to believe that ANet would be making these structural changes to play and not compensate in the event reward system.

FFXIV ARR does what you are asking OP. Except a lot of it can be cheated by spamming heals etc… it is hard to make a perfect system for recognizing ALL contributions. Instead of DPS maybe they mark # of abilities going off (weather successful or not)
Well, when it comes to loot, credit is pretty much a binary thing. Either you did enough damage to tag the mob for a chance at loot, or you didn’t.
If anything, that gives more of an advantage to classes with AOE and wide cleave attacks regardless of builds. (So Ele and Engie tend to average out more loot from mob swarms than Mesmers or Thieves might)
I assume in the new system depleting the defiance bar will be just as good for tagging as doing damage.
So it would be nice if you also got a mob tag by healing and buffing the actual attackers. But I don’t know if the mob tagging system is quite sophisticated enough under the hood to detect healing in that manner.
This is a change needed for WvW, too. I’m not touching Ventari or his tablet unless they start rewarding credit for healing, something every other MMO has had implemented since launch.
