[CHOSEN] Game mechanics. (help a noob)

[Lethiel]

New Chosen with 2 questions:

1) is it worth (in pvp) to have negative chance to be crit therefore stacking Flawless armor and initiative/reduced chance to be crit?
I see some chosen running full ini talis and i have no idea if it's good to go like -15/-20% chance to be critted. how does it works?


2) for pve tanking single target max aggro do you just spam Enraged Blow and keep up Oppression+Suppression or do you also use dmging dots and toot of tzench? what is your pve tank single target max aggro rotation? (also do you keep taunt and challenge for when you lose aggro due to mech/when needed or do you include them in the rotation?)

Thank you all for your help.
