Sharding eliminates server load and realm stability. Cross-realm sharding is here so that players are evenly distributed across realms and helps combat underpopulation. Sharding at launch is vital to ensure a stable launch of an expansion. Starting zones would be filled with millions of people and that would turn even accepting a quest into a nightmare. Disadvantages of Sharding
In order to save up gold quickly, you must be mindful of your character’s professions. According to various sources, the most profitable profession back in the day used to be herbalism. Mining and skinning are right up there as well. Gathering-oriented professions have an advantage compared to the crafting ones in the early levels because gathering doesn’t require you to spend gold in order to make some coins. You can find plenty of herbs to collect, ores to mine and beasts to skin, all while you’re levelling. Everything you manage to gather can then be sold in the auction house fairly quickly.
Another way to make gold. This option works well at level 60 when you have some good gear already. Obviously, you should have some gold ready to buy reagents. Be ready for expenses up to 225 skill points in any profession: items below that are not worth much. You will get first income after 225 skill points in Leatherworking, Blacksmithing, Alchemy or Tailoring. Unfortunately, Engineering and Enchanting will still require some investments. The only way to make gold with enchanting is disenchanting skill (we talked about it).
With the Classic beta now out it seems every related article somehow manages to spark the eternal war of "Vanilla was the best WoW sucks now" and "lol nostalgia goggles, Vanilla sucked, enjoy your two weeks of Classic". I have to say, even though I understand the principles behind the battle and the reasons people behave and talk this way... I actually REALLY don't get it on a deeper level.
Where to get materials and reagents you may ask? Buy for cheap off farmers in bulk or track Auction House lots. Get in touch with most big sellers. Communication is important here, send a whisper or write them a letter. It would be good for both of you to establish business relationships. Constant suppliers and buyers is convenient for both parties to save the time and effort.
