I personally wouldn't recommend Bloodmyst Isle. There's a ton of quests but a lot of those quests have absolutely horrible drop rates on their items. A lot of the quest mobs also have very slow and/or spread out spawns so if there's other people there you're gonna be waiting for respawns or spending a lot of time traveling between spawn areas quite a bit. Overall it's just an incredibly slow zone as far as EXP goes.
A "stat squish" and "item squish" was implemented to lower the numbers used in the game, e.g. a legendary item previously with a level of 1000 reduced to 265. Unique class-specific buffs are added back, i.e. mages' Arcane Brilliance and priests' Mark of Fortitude. Titanforging—a random event that raises the initial item level of an item gained via drops or rewards—is still in the game; however, if the item is one of those affected by the Heart of Azeroth, then that item cannot be titanforged.
To use it as an auctioneer, send all your auctionable items from your alts to your bank alt, and organize all your auctions from this character. This saves your time spent on auction house management, focuses all your income to one character and allows for easier overview of your cash flow. Consider using an alt management addon to be able to access all information about your alts from your bank character. One such addon is Altoholic
While leveling, try to make use of the new Battle of Azeroth experience gem, Insightful Rubellite, which gives you +5% experience. Equipping one of these requires a socket in your gear, so try to hold on to a piece of Legion gear with a socket or acquire one of the Legion Legendary rings since every class has one. Each of the rings includes a socket. You can acquire one of these rings rather easily by doing World Quests in Legion zones and acquiring 1,000 Wakening Essences that can be used to purchase a legendary ring in the Legion version of Dalaran.
I highly recommend actually staying in the 20-60 range zones until you ding 62. The reason for this is that despite getting a slight penalty in experience for being over-level, the advantage of having flight will more than offset this. That, and WOTLK and TBC zones are the slowest part of the leveling process. Minimizing your time there as much as possible is worthwhile.
Hey Bunnycuddle, big fan of your approach to gold making. Due to recent drop in obliterum market prices i have started exploring the best flipping possibilities out there. I found one very interesting phenomena that proved to be very profitable on my server. Basically due to it being least desirable gem Versatile maelstrom sapphire tends to drop in price on AH well under 160g per piece, and while oblierated it gives 16 ash in return. I think this is something you could possibly research in your future post and give a little bit more in depth analysis.
4. Is there a guild waiting for you on the target server that you are satisfied with? Often times, I have transferred to a server, made a lot of gold and quit the game out of boredom because I was without a guild. Another aspect behind this question is that often times in guilds, you can get free flasks and materials to craft goods instead of spending your own gold. This will add up in the long run, whether it's free repairs or free abyss crystals. Remember, you can always send the crystals to another toon and sell them for gold as well.
The most simple thing is TradeSkillMaster. This AddOn shows you quite an amount of information in the items tooltip. In my opinion, DBRegionMarketAvg the best source. It tells me the price, an item was posted on all EU realms in the last 14 days. Why not DBMarket? DBMarket only shows you the items value from your server in the last 14 days. This value often gets manipulated. Some people start to post an item with a 500g value for 500.000 Gold on the auction house for several weaks. As a consequence, DBMarket is rising towards 500.000 Gold. If you use DBMarket with 100% and post your item for 500.000 Gold, nobody will buy it.
