ап!http://ru.wowhead.com/spell=81229 прокает,но откатывает руну которой осталось до восстановления ~1-2сек.должен откатывать полностью исчерпанную руну.
More like saying that Mark of Supremacy is a cheaper version of Deathbringer's Will. Runic Empowerment is a proc, ERW is a cooldown. Most likely Runic Empowerment is meant to add a random effect to a DK's rotation. As you should know, in Cataclysm, the second rune of one type (blood, frost or unholy) that is used only starts refreshing after the previous one of that kind has finished its cooldown, and this proc basically halves that time, since the depleted one can become active even before the other one has come off cooldown.
The interesting thing I find about this proc is that since it's in the first tier of the frost tree (at least how it is in the current beta build), and judging by the abilities it procs off, it is meant to come as a possibility to change the playstyle of any DK type, and IMHO this is a breath of fresh air in the landscape of the pretty standard 41-point talent trees.
