Sorry if this has been answered elsewhere. Did a little digging, no luck.
Ok to the point. For T9 (From my understanding) Helmet was the odd man out for the Prot set.
Given the following facts.
Capable of doing 10 and 25m ICC.
No (as of yet) access to Heroic Tier Piece Tokens.
Which of the Tier 10 set is the "odd man out"? And can be better replaced with something (Purchased with Frosts, Made (Blacksmithing), or dropped (25m Helmet/Pants).
