Every group and Rogue will have a different perspective of the fight, and different strategies. I tried Combat and it just really didn't feel right for the fight. I AoE plenty towards the 4 adds mark and if you're putting Rupture on everything your energy will feel just like Combat. On 10 man the focus is more on the boss than the adds, and having the higher single target damage is a lot better. I'm also the one in my group where my slow does not change or nerf my damage, where as other classes have to spend resources and GCDs to do it while they're compromising their positioning.
I'm currently uploading our Sha kill from my PoV if anyone is interested to view it once it has completed
