Glyph of the Empowered Undead
Before I explain what the glyph is or what it does, I will say that in order for the glyph to be implemented, the 5.2 DK damage buffs will need to be reverted and their damage as it is now would need to be nerfed slightly. A lot of people will flame me for this topic but it's just an idea and I'd like to know your thoughts on the glyph and whole idea.
So basically, DK defensive isn't that strong, once AMS is down, you're in trouble and once you've walled (IBF) it's pretty much gameover. AMZ is something you have to talent for so I'm not sure what to make of that. I took a look at the defensive CDs of some other classes and also offensive CDs of some classes and came up with this.
Army of the Dead useable in arena. The glyph will make Army of the Dead instant, increase each ghouls damage by X% but reduce the number of ghouls to 5. It'll also act the same as Mirror Images, dropping you from everyone's current target the same as Mirror Images. Now you can see why their damage would need to be nerfed because we all know DKs are extremely strong on the offensive right now but are too weak when getting focused.
Main inspiration for this glyph is Mirror Images and obviously stampede or "zoo". Just thought I'd mention that before anybody says that instant Army of the Dead is stupidly over-powered.
