Not be hitting a brick wall
In general, Ulduar will be harder than Naxxramas is. Naxx was tuned easy RF CP on purpose, and the devs have been saying for a while that Ulduar to the same extent will not be that way. Ulduar is the second year class. So we will not be hitting a brick wall, but it probably will not be compared to UBRS either like Naxx often is now.
