I've been wondering what glyphs are worth using in PVP as Shadow. Dark Binding is obvious, but that goes baseline in 5.4. If you're facing Mages/Pallies glyph of Mass Dispel might be worth taking. But what about others?
Personally I use Inner Sanctum and Prayer of Mending to stay alive on instants when being trained (BGs and low-rate 2v2). Fade seems to be an option, but it's up only 1/3 of all time. Inner Fire doesn't look too promising - not many classes left that deal physical damage almost exclusively and those classes usually have means to bypass armor. SW: Death is said to be good against Poly and probably some other CCs.
In US Priest forums there's a sticky PVP Shadow guide, which states that Reflective Shield glyph is a really good one, but is often overlooked. Is it really good or will it be in 5.4 with its percentage boosted to 70%?
Anyway, I'm new to Priest, so would appreciate if more experienced players shared their opinions which glyphs are worth taking.
