What they mean by "change the damage calculations of tanks"?

I would be interested if SE went the route of having tank accessories do tank like things -buffs/debuffs etc. Though this would be less "flashy" than options more skewed to putting out moar deeps, Accessories that mix and match various buffs (dmg down, magic down and so on) would allow us to keep our right side gear flexibility.

One issue I see with that is, either the effects would be so minimal as to not really matter - or they start to encroach on balance. Like, we know drk is better with magic mitigation, but now you can have war or even double war stacking magic down thus eliminating the need for drk (and possibly pld). So you don't want to get in that situation, you still want each job to have it's niche.
