I just bought a Crimson Deathcahrgr for 65k
how much do you guys think it will be worth in cata? should I use it or keep it
This is one of those annoying "I'll reply even though I can't answer your question" responses
It's hard to say one way or the other because I haven't seen any definitive answer on what is happening to the shadowmourne questline. I will assume it will remain, as with most other legendaries, although I think they will perhaps change how you obtain shadowfrost shards. The major point being, we have no idea if killing the lich king after obtaining said legendary, will still result in a chest and the vanity items, if this is removed, then the mount is going to be worth perhaps 10x that amount! ... if the reward chest remains, then it's value will most likely DECREASE due to how easy it will be to farm.
My advice is to hang on to it, wait for clarification of what is changing (if anything) with the shadowmourne questline, and reward for killing lich king with shadowmourne, then if a) no longer obtainable = SELL... b) still obtainable = USE, or sell for what you paid and then go farm one
