I wanted to take a quick moment to discuss why the level 75 tier for Death Knights still exists. I remember there being like a massive 30 or 40 page thread talking about this during the MoP beta and most of the feedback was concerning three things.
-There will always be a best choice for any particular spec.
-Why is it so high up in the tier for low lever players just starting
1. Blizzards first explanation for making our core rune regeneration as talents was because they wanted us to be able to use the regeneration that we wanted for any particular spec but it never worked out that way. Blood always took RC, Unholy Always took RC and Frost always took BT or RE depending on if they were 2H or DW. The illusion of choice there has always been noticeable.
2. If in fact DKs retain this tier going into WoD, why should it remain so high up in the tier that new players or just starting DKs don't get a core DK mechanic until level 75 which is just dumb and also leaves a bad taste in the players mouth making the class seem week or too slow.
3. Where is the fun in picking a straight up passive ability in which should already be a standard passive ability for the three Death Knight specializations. I don't see any other class in the game that has to waste three perfectly good talent spots to choose how they regenerate their core resource.
Overall I feel that this tier needs to be removed. There is absolutely no reason why this tier ever needed to exist. The entire point of playing a particular spec was because you liked how it felt and played not because it had any one specific resource regeneration mechanic. Not once during cataclysm did I ever see a Death Knight complain about 100% rune regeneration for 3 seconds in unholy and vice versa for the other two. I simply want to appeal to Blizzard and ask them replace this tier with cool non boring abilities because I know they read these forums.
If anything they just need to make BT baseline like it was in Wrath and Cata.
This guy said it better than I could.
To me this tier, BT in specific, goes against everything blizz has been trying to do for two expansions now. These talents arent fun and in no way add depth to the class. Most DKs I know just take RE or RC to avoid the hassle of BT and those, like me, that do take BT just macro it into some other abilities so that it is a hit and forget aspect.
