I was curious, is it better to have a slow offhand or a fast offhand as a subtlety rogue at 90?
There is no such thing as a "slow" or "fast" dagger speed anymore. All daggers have been normalized to 1.8 speed with the exception of the level 80 Kaluak rep dagger that is 1.7.
In regard to the question above about racials for Alliance and Horde, if you give me a day or two I will run some numbers and get back with an answer. I will update this post with information when I have it.
Someone can confirm this race ranks at the 90 ?
Or there is a spreedsheet to simulate ?
Does anybody has an insight as to at which point it is worth it to break the 4xT13 HC set? And a similar question about when to replace the Fangs?
Can you please be more specific with the information you are wanting to know. What spec are you referring to? In general just wait until you can buy the 450ilvl pvp or justice gear at 90 and that should sufficiently replace the t13. You "could" do it sooner, but to try and simcraft every possible combination of leveling gear is incredibly time consuming, nearly impossible, and most importantly, pointless.
As for the daggers...
- Assassination: According to my simulation numbers and backed up by in game testing, not until you have double 463ilvl daggers or better.
- Combat: Any combination of 450 Weapons should be fine as long as you are using at least a 2.6 speed main hand. Optimally you would want both weapons to be slow, but the difference is minimal. You won't start seeing any real difference in damage until you get at least one 463 weapon since the gain from legendaries to 450 weapons is less than .001%
- Subtlety: Same situation as Assassination, it's not worth the switch until you can equip dual 463 daggers.
We complained about not being able to use our legendaries for very long but it seems we may be able to get more use out of them than we thought.
