I'm very happy that I finally managed to reach 5 million gold and get my longboy mount today. I'm back to 0 gold again, but I feel it's worth it as I spend a lot of time on the AH with my main and alts. Plus it's a big, great looking mount. Do you have yours already? Still trying to get it? You won't be able to buy it when the pre-patch comes. It will after that move over to the black market AH, where it will definitely cost more than 5 million. Sell everything you have. Hand in emissary quests. Clear old raids and sell all the loot. Do world quests from Legion and BFA with pvp mode on. If you're desperate, sell tokens. Good luck.
