I think this goes in here, if not can you move it please?
We are all assuming that DK's will get new abilities and some remodelled talents, my suggestion for one of these abilities and talents.
Ability: Runic Revival (Yeah I know, names on the poor side):
Basically acts as a DK's "Oh shit button."
10 minute cooldown: Refreshes all cooldowns from runes, making them available to use again. Possibly a glyph to half the cooldown time.
Ignore this as I forgot about Empower Rune Weapon.
Talent: Deal With Death (Again on the name, it's either this or Runic Recycle.)
3 Ranks.
Each time you use an ability, you have a 5(10)/10(20)/15(30)% chance to not use the rune(s) or runic power needed for an ability. The numbers in brackets could be the gain you'd get from a possible glyph, although I ain't too sure if you get too many glyphs based on talents, if any.
