Daelo je našao vremena idao nam je odgovore o težini istance Ulduar kao i achievementima koje nas čekaju za novu istancu (Source):
The reward for completing the hard modes are not going to be just
achievement points, titles, or mounts, but improved, additional item
rewards.I think it's safe to say that Ulduar will be a bit more difficult overall than Naxxramas, even without the hard modes. We're still going to tune the zone for accessibility(*), but a raid group that's done Naxxramas, Malygos, and Sartharion and obtained the gear from those encounters should be well prepared for Ulduar. Not only is the raid's gear better, but players should now have some raiding experience under their belts. We also have a much more accurate picture of what guilds are capable of from a healing, damage, and tanking perspective then when WotLK first went live. If Naxxramas was the introduction to raiding 101 class for players who have never raided before, think of Ulduar as the second year class.
* There will be one optional encounter that is only tuned as a "hard mode" encounter.
I don't think you have to worry about spoilers from Achievements, to be honest. Seeing achievement text before you fight a boss is like seeing a single piece of a large jigsaw puzzle. Sure, it's something, but it's nothing really without seeing the context of the encounter as a whole. I also expect achievements to be something tested late in the PTR process. Implementing them is one of the last parts of the development pipeline.
