Depending on your spec, MM priority will change a bit. There is no Chim-SrS anymore, so if you use chimera, it's not necessary to apply srs before. However, if you use a serpent + arcane spec without chimera, then I suppose feel free to cast it first. I am talking about completely not using chimera, and probably speccing into imp serpent. Unlikely that trading it will be worth it, but its an idea to test out in the future.
buuut in general that priority makes no mention of imp steady which is actually very important to keep up
Glyphs need to be updated; arcane is 12% damage ( dont think it needs serpent too), steady doesnt require serpent, serpent is +6% crit chance, rest looks fine
mastery is strange- for bm i think its effect is severely diminished right now, but for mm and sv it is quite worth it. you may want to include the small tidbit that reforging will always be 40% of a stat to another, so you can plan ahead
