It has been said by the Devs that with the rune system overhaul, there will be more space in a DK's rotation. While this isn't a huge problem for DPS DK's, I can see it becoming quite problematic for tanking. It is already quite annoying waiting for the CD on D&D or HB/not having runes up when adds come in, and with more space in the rotation, I can easily see DK tanking (especially on adds) become more rune-cd dependent. If we hit a "space" in our rotation, and then adds come, you are pretty screwed (assuming that you've used Blood Tap and ERW recently). I came across this thought while tanking the Tribunal in HoS.
How do you think that this should/will be handled? Do you also see the new rune system as problematic for tanking?
I usually tend toward optimism that the Devs will handle things well, but I'm really curious as to how this is going to work out.
