Note - I have updated this thread with all new information and factual evidence that backs up my claims that all talents are picked for us and we have 100% no choice in talents.
I know that most of these issues have been presented in many other various threads but I just realized something and came up with a dramatic conclusion about Death Knights going into MoP.
We have almost no choice in talents/glyphs at all.
Lets break it down.
Lets start with your talent grid.
Tier 56 - This tier is all about spreading diseases. Then we have a talent in their called plaque leach which lets us obtain a Death Rune in return for diminishing the diseases on our current target. The automatic choice here is Plaque Leech do to the fact it gives us a death rune. The argument here is that we have plenty of other mechanics to spread diseases such as outbreak and pestilence so doing more dps is the obvious option.
Tier 57 - Nothing really to discuss here. Purgatory will be mandatory for tanks who obviously want to survive and live long as possible. AMZ and LB are basically just their for PvP. Most if not all dps will choose AMZ in PvE because they will want that raid CD. There are no situations ever where a dps would want to use LB in raid situation. And of course a PvP player will always take LB.
Tier 58 - Now this is a tricky tier because of the change to frost presence. Now that frost specialization is forced into frost presence we now lose the movement speed increase from unholy presence. Because of this, everyone will spec into death's advance for both PvE and PvP because of stacking speed increase buff even if you are unholy. Not to mention that glyph of DnD lets us slow anyways so CB is never an option. Asphyxiate which I bet sounded cool to everyone at first when it was announced but further glance you notice it gets rid of silence. No one will ever choose this outside of cosmetic playing around because we would rather have a silence+a movement increase than a stun that most are immune to anyways.
Tier 60 - This is another no choice tier because it has already been mathed out. You are 99.9% of the time going to want to pick death pact because of the way it functions now. Being able to heal yourself for half your health instantly is an automatic win even if you are not unholy because raise undead is on a 2min CD same as DP. Conversion and Death Siphon are both useless in both PvP and PvE because they are a dps lost because they costs enormous amount of resources. Conversion might be used for leveling without having to wait and eat but even then Death Pact is better.
Tier 75 - This has been discussed for months at it is pretty much unanimous at this point that no one wants this tier. Having to choose a core mechanic to decide how your runes regenerate is just not a good idea. I mean you wouldn't have a healer choose how the regenerate mana or a pally decide how they regenerate holy power right? This tier has already been mathed out as well. You are always going to pick RC if you are frost and RC if you are unholy just like it is on live. They need to go back to how it is on live currently. Make BT baseline and assign RC and RE back to frost and unholy respectively. Then replace these with 3 more interesting talents.
Tier 90 - This is a completely useless tier, even for PvP players. Anyone who has played their death knight for more than 5 minutes can notice that these uninteresting 90 talents are just updates to talents we already have on live. Remorseless winter is actually just hungering cold except worse because of the ramp of time as where HC just had a 1.5s cast. Desecrated Ground is just desecration from the unholy tree on live except we are immune to CC which again isn't really a big deal we need to be mobile. Mass Death grip is cool, but again is auto choice for tanks. DpS could live without either of the other two.
Now lets talk about glyphs.
It has been discussed already that death knights just aren't getting any good interesting entertaining glyphs unlike other classes. Lets talk about mandatory glyphs.
Glyph of AMS - Why would you not want this as tank or dps in PvE and PvP.
Glyph of VP - I thought we were trying to avoid straight up bonuses to spells in MoP? All tanks will take this just like they do now on live
Every other glyph is just iterations of things we already have on live, just boring.
Death Knights have been voicing their issues for a long time on the beta forums and none of the issues have been addressed aside from number issues. Please give us interesting mechanics and abilities. Druids, warlocks, hunters, Spriests, and shamans have received borderline class overhauls while we are left with crappy talents we already have on live. Please Devs, fix us.
