An issue I have with steps one and two are that it basically makes penta-melded gear bis and thus people will be ridiculed for using tome accessories.

The simple fix is if enmity generation stacked with VIT only then it would stop dps from complaining about tank dmg and make sure that fending becomes useful again.

As far as parry goes, it's a terrible stat only because it scales poorly and is calculated by SE's famous RNG machine. Parry and block are great traits but are poorly implemented and are simply reduced to icing on the cake as far as mitigation is concerned. That and coupled with the strength of such cooldowns like Bulwark and Raw Intuition, parry outside of cd's are essentially a wash and either needs to be increased or removed entirely as no tank in their right mind would take it outside a mt DRK who needs it for LB procs but even in this scenario its questionable.
