I will, however, offer my thoughts on the glyph. The first and largest thing that I see is that with the glyph you can use pestilence to refresh both diseases. This means you only expend one rune and one global cooldown instead of two. You're accomplishing the same goal but using half as many resources to do it. Then with the rune which you have not expended in refreshing your diseases you can use a heart strike (if you have a blood or death rune remaining which is usually the case) and potentially get a death coil proc, or you can use it toward your next death strike (if your remaining rune is frost or unholy) which will ultimately give you death runes.
