Hello!
I have reached a gear level, where I have a significant amount of secondary stats to juggle around, and was wondering what do you think about the value of crit vs mastery and spirit, and also the overall value of spirit. I'm currently sitting on ~40% mastery unbuffed, which makes it around 46% buffed, making the additive mastery modifier along with Naturalist ~1,56. Btw, is naturalist still additively added with mastery? It was in cata, before they removed it, so I assumed so.
My current spirit is 11k, having reforged it all away, as its present in pretty much all gear. Do you think that's too low? I do run OOM sometimes, but I think the added throughput is more useful than having the possibilty to continue spamming a bit longer. What do you feel is a good level if spirit for yourself? Do you think even I oom sometimes, low spirit - max throughput might be a good thing?
My current unbuffed crit is 16%, so add raid buffs to that it becomes something around 22-23%. I don't run the glyph of Regrowth at the moment, I have stampeding roar or innervate glyphed in place of that. So if we compare the two values, becomes easier to gain 1,23% crit through combat ratings than 1,56% mastery, for an average 1% more healing. Of course there are some variables that make it less simple than this, like the fact that shroom bloom can't crit (though the base healing of shroom accounts for quite a small amount of heals) and the fact that Regrowth has an additional 60% crit chance.
Playing a resto druid, I personally don't share the opinion of the randomness of crits making the stat less valuable (you could argue more crit makes Regrowth actually more reliable), as hardly anything ever depends on having a single hot tick crit or not, and a lucky crit might as well save someone in a tight situation where slightly more mastery wouldn't, as it could be the other way around.
TL;DR: When you get enough mastery, crit can become as valuable as mastery. Value of spirit seems a bit low at high gear levels. (at least for me).
