Your damage will come from shocks, fire totems, and the optional natures - swiftness / chain L. combo.
you trade the big crits from elemental fury for the higher average damage to spells and healing from natures blessing which is good for pvp since resiliance reduced crit damage and crit chance as it is. its also good for pve as you dont spike in threat.
if you are attacked by melee your game is to drop fire totem, shock, and heal between the shock cooldowns.
you will go full + dmg gear, but some + healing wont hurt as it adds to earthshield healing and to +dmg now anyways.
Season 1 arena set is also nice in that you get 70 chance to stop interrupt while casting lightning bolt.
with approx 10k armor, 10k health, and earthshield, rogues are nullified.
