To be honest my opinion is that since ive been playing as a trooper vanguard tank in PvE the best thing to do is ignore gear names, and aim towards initially reaching full 66, then develop your vanguard into 69 rated gear with focus on these:
Defence chance: 17-18%
Sheild chance: 30-33%
Absorb chance: 30-33%
Accuracy: 98-100% no more other wise its a waste.
remainder goes on endurance, aclarity is irrelevant for a tank tbh.
After this concerntrait on getting arkanian drops in operations to gain a set bonus, and eventually move towards building up to 72 rated gear without losing the percentages set.
I know the percentages seem low at the moment in comparision to before 2.0 but realistically the vanguard tanking has become more, ability and rotation dependant as a result of energy blasts new 25% absorb increase and changes to other abilities this makes for a much more constant higher stats during combat rather than the previous burst defensive cooldowns. (reactive shield is still the best defensive cooldown of the class)
Relics should also be considered, have on which is defence chance and the other absorb/shield chance. make sure that one is an equip/passive relic the other you can use as a defensive cooldown if nessicary in combination with riot gas.
This is how i choose to tank and believe its the best method here of how to set up your class for 2.0
any questions just ask
