Sweet, thanks for that. Should I be aiming to get that surge/crit from Jugg gear or Mara gear?

Lol OK, this seems pretty important so imma just jump in here and be that noob asking for a quick protip: I'll be turning 50 very shortly with approx 2500 RWZ comms and 2K WZ comms. What should be my first pvp purchases, or alternatively, what sets/pieces should I be aiming for first? Pvping as Anni.

Sup Warzior's I've been cruising through pvp on my Anni Mara from 10 to 49 and I feel I've got a pretty good handle on managing the buffs and damage output and all that. There's just two abilities I'm not as certain on, as per thread title. Retal and FS. I've done a bit of research but couldn't find any conclusive or current discussion on it so any input is appreciated. Essentially, I want to build stacks of fury quicker without losing damage per rage. FS is a nice bit of extra damage when I've got that sorc down to 10%, my interrupt and charge are on CD and he Overloads on me and I need to finish him before he gets that heal off... Etc. Should I ditch retal and FS and stick to vicious slash when annihilate/rupture/deadly saber are on cooldown? Cheers
