Prot Paladin, Advice welcome. Glyphs/Gems and a shoulder Question!
My strat, and what seems to be the most common strat for pallies starting in gear is mastery heavy but not exclusively mastery.
Red=parry+mastery (fine ember topaz)
Blue=mastery+stam (puissant dream emerald)
Yellow or prismatic=pure mastery
This is of course assuming the socket bonus is a tank stat.
Every piece of tank gear should have dodge, parry or mastery. Some dps pieces are hard to tell and may make a decent filler piece. Socket bonus is often a clue. Some alternate tank pieces may be mastery+hit or mastery+expertise. If it has haste, crit, agil, spirit or intellect it is definitely not a tank piece. Don't be concerned if you have to farm regular dungeons or reg heroics for some time before stepping into a zandalari. Those are a significant step up in difficulty.
