It's not just the 75 lvl talents, the runes themselves do not work properly. Fixing the runes is important because they can make the DK really OP or really weak depending on witch 75 lvl talent you are using, like with runic corruption you can use all of your runes while it's up and still have fully recharged runes which is really OP because you can stack an insane amount of necrotics whit it, while with Blood Tap you can have 10 stacks of it with all of your runes on CD use it and still won't get a single rune back.
If you want balanced Death Knights the rune system must be fixed along with the 75 lvl talents, if not some Death Knights can abuse the living fuck out of it and do insane damage/necro stacking/healing at the same time.
Pujo did not make a good thread and Noneedholy is acting like a child and he flooded it, so it needs to close and Pujo or someone else needs to make anther thread.
