Personally I'm disappointing that you have to decide between Shadowstep and Prep. I'm not sure what model blizz is going for PvP in 5.0, but this feels like a step in the wrong direction to try to get more people interested in playing rogues, on either PvE or PvP side.
I would have to agree with this. Mobility has been and issue and this seems to limit it more than ever for PVP. However, I think the choice is extremely nice for a PvE setting. The ability to use prep as any spec seems to be a very nice addition to the PvE rogue imo. There are a lot of fights in the past where having double cloak could easily have saved a rogue. Additionally, an extra vanish and sprint won't seem to bring additional utility for rogues, especially if you take Subterfuge or Shadow Focus. I think Preparation would be my go to talent for PvE (of course, this would depend on how they design encounters in MoP, but I think the added benefit of double cloak/vanish outweighs that of teleporting to a target and spending 60 energy on a sprint).
I wanted to make sure I am reading the new Killing spree correctly. If I am reading it correcly, you get to use the ability and generate an instant 5 combo points on that target. If that is correct, it seems pretty nice. I would guess you would get 15 free combo points out of it, assuming you used it then the finisher each time. Anyone else reading it the same or differently? I think past discussion has pointed more towards you get 5 cps over the course of the 5 seconds. This may be OP for PvP. Having 15 combo points in 5 seconds, along with the damage it deals, seems like a way to instagib someone.
Along with KS, Vendetta seems really nice for both PvE and PvP. We all know th trouble of ranging a boss/enemy. Not only does the talent give us increased damage, it also lets us deal with those times where the boss it OOR fairly well. Granted, it isn't going to produce the greatest damage, but some damage is greater than no damage. It is hard to say how useful it will end up being in the beginning of MoP, but I would see this being very useful on specific encounters.
While there is some lack of useful talents in certain tiers for either PvP or PvE (i.e. lvl 75 for PvE, unless the have an encounter like H-Nef where crippling poison was OP), I think these new talents will bring some interesting playstyle to rogues.
As far as talents go, I am a little worried about what they have listed on the site. Currently, I am not seeing passive abilities for things such as imp SnD, Precision, Agression, Savage Combat, Ruthlessness, etc. I am sure there is a whole list of other ones, but I was specifically looking at the current combat build vs new talents for rogues. Do you think that they are removing this sorts of additions from rogues, they haven't been implemented yet, or they just want to remove them? Thoughts?
