If your trying to spam denounce its a good set up. But for heals I'd go a different route on shoulders ,head,both rings,bracer, belt, trinket, boots, skinning since crit is important to pallys.
Your pally looks more geared for dps than heals. If thats what your going for than it looks about right. I'd be worried about u getting stunned by a pally or feared n then ambush and 2 shotted while stunned or fear due to low hp n no pvp trinket to pop out of.
