Okay. I said it before I'll say it again.... this needs an update.
I'm not sure why it's pooling so much runic power but for shits and giggles (after watching a lot of notmes steams on twitch playing his dk) i'd play without the CR.
I'm literally doing more damage without it. I'm actually using frost strike getting blood tap charges and using them at least 60% more than the CR does. because of this a lot of rune regeneration is being wasted.
Please look at logic behind using frost strike and lvl 60 talent tree.
I dont know about frost but unholy has amazing dps...
