Upgrades and ICC tanking.
So tonight i will be tanking ICC 10 for the first time (probably just the first wing) Now I've been told a few different things, because my GS isn't above 5400 i shouldn't tank anything, also that as long as i'm over 4.8k (i think i'm around 5.1 right now) I should be fine as long as raid groups listens and has a basic understanding of the fights; looking at my gear should i be fine tanking this?
Also i'm saving up frosties for a piece of t10, i am deciding between shoulders and helm, if all goes well this weekend i should have enough for shoulders before Tuesday; should i wait for helm or get shoulders? (i have the pants from voa10, and I am running voa10/25 until gloves drop).
Thanks everyone in advance for your help!
