Might be able to finally get the Black War Mammoth.
I've said this before and I'll say it again. I have solution to make both sides happy for the whole should things be removed or not. And it's quite simple. First of all, do not change the original philosophy of the game. Keep things that were removed, forever removed in Retail and continue making limited time content rewards. Then, keep a rotation of Classic expansions rolling. That way if players missed out on an item, title, achievement, etc. they can play on those servers and still get it the same way it was originally intended. Finally, allow collections to be cross-over. So if you got something on a Classic server, you can then use it on Retail. This way items can still be obtained without devaluing them. So if you want the Black Proto drake and Immortal title. Then you go back and play Wrath Classic and earn it the same way it was originally earned. Then you can preen on it in Retail.
