Either way the same would apply for any job, but more so for healers and tanks for everyone's benefit. They should, ideally, stay in tip top shape on the way to max level as best as they can.
You can have the best tank gear avalaible, if your dps hits like a wet noodle you'll run out of CDs pretty fast when it comes to tank trashmobs.
Dps gear is as important as the 2 others.
