In a thread on the tank forums, a monk posted the following (it was in a discussion of why tanks have different sized HP pools, in which in addition to pointing out the obvious variations in stam multipliers, someone claimed that plate tanks are more likely to gem stam because they have fewer other good stats to go for):
Not just sockets, leather tanks usually go for agi enchants, food, and flasks over the stam counterparts.
I don't know if he actually intended that to apply to druids too, but my immediate reaction was "I don't think I've ever done that", which was of course immediately followed by "Should I be doing that?"
I thought that agility isn't what it used to be and, in fact, is now a fairly low-priority stat when you take into account the amount of other stats you have to give up to get it (usually 1.5:1 stam and 2:1 secondary stats). Although it looks like the scaling on wrist enchants is kind of screwy, as you can actually get slightly MORE primary than secondary stat. So I guess in that case it is worth it.
It looks like you are in fact using agility leg and shoulder enchants, while page 1 of the guide still advises stam. Do you think this needs updating, or additional discussion of when to use each?
Of course, the armory can't show what consumables you use, but the guide advises stam food and either armor/mastery elixirs or the stam flasks. Is that still current information?
