No, because there are always either 1 or 2 tanks in a given party. VIT is the tanking stat. Tanks either get all the tanking gear on an instance where they solo, or they compete against 1 other tank. Regardless of how many tanking classes are added, that doesn't change.

However, there are 2-6 DPS in any given party for content, and among them there is variance in primary stats. This variance has to be balanced to a reasonable degree.
