I disagree, I would also say that the 4 titles need to be removed as well. This is coming from a player that does not have, undying, Immortal, of the Nightfall, or Twilight Vanquisher. I believe that even if you imposed the i-level requirement it still defeats the hard work put into this achievement.

Now of course the majority of the player-base will not get these mounts, but I say that is what makes them so beautiful. I have wanted a Black Proto-Drake ever since I first step into Naxx. The excitement and anticipation ever week when we try this achievement or that made the fails bitter sweet but I honestly felt like I was working towards a goal, even if in reality it was unreachable.

If I log on a month or two after the patch and I see everyone sitting outside Dal on a Black Proto-Drake all those nights become wasted. I honestly believe that there should be some things that not everyone can have. Why? because that great night when things go right and you get that one item you can have it with pride and a sense of accomplishment.

Here is what happens when you put in the i-level requirement. Patch hits everyone goes to Ulduar gets the gear they need to make Naxx easier then people get the BiS for that i-level. Then i ask you, hasn't the Ulduar i-level affected people's ability to get the Black Proto-Drake, therefore cheapening it? Please do not fall into the trap that people are not going to go to Ulduar before they have their Black Proto-Drake.

Its not a matter that those that do not have the mounts yet are bad, its a matter that no one is going to sit around in Naxx week after week grinding out these Achievements when they can be in Ulduar.
