As for now (and the near future) LFR will offer 2 weapon choices for tanking DK. Those are:
Starshatter (Elegon) - being quite good, although it lacks its own mastery
Shin'ka execution of dominion (Sha of Fear) – most desirable weapon blood DK can get now.
Current loot system distributes the chance on getting loot depending on the spec of each particular player. In this way, the system limits players from getting other spec gear (let's say Prot pala is unlikely to get spirit plate shoulders). The question is: what is the 'spec-type' set for these weapons? Do I have a chance to get those if I sign as tank? Or I can have one only if I'm dps.
Although the questions might seem quite obvious for some people, I do still have a feeling that the system blocks Starshatter from being lootable for blood in LFR. Would like to know for sure before I spend lucky charms on the attempts to get Shin'ka.
Thanks a lot in advance!
