I'm not a fan as the only time i enjoyed tanking was when healer was downed and i got to keep other dps alive (not 25 minute solo mind you)
It's a change to cater to making dungeons more easy despite that they already are super easy lol.

Honestly it's just another excuse to not actually fix healers and Tanks, Tanks shouldn't be able to really survive without a healer in the first place, now that you can have Tanks rez even doing things for the first time you likely would want to bring 1T 3dps now because you can rez (or heck 2tanks if your worried about survivability)
