With the exception of wow gold, force you to need items from other crafting professions.
What I mean by this phrase is that when you choose a crafting path, you should be able to create anything you want from that specific crafting school and not rely upon other crafting schools. If I choose Leatherworking, I should be able to craft some wicked leather armor and not need items created by a Blacksmith or a Tailor. Yet, all of these games, with the exception of wow gold, force you to need items from other crafting professions to make certain items. They do this to promote "the social experience and grouping dynamic," but we know the real reason. Again, it's another time-sink where you'll either grind out some gold to buy the needed mats from the Auction House or create an alt that has those needed crafting professions. It's utter crap. If they want to force you to need items from other crafting professions, then they should allow you to learn those other crafting professions and not limit you to 2-3 professions.Since WoW relies only upon a general crafting level, you don't have that problem.Besides,we always provide cheapest WoW gold to player no matter they are in Alliance or Horde. Plans for a cool hammer.All Recipes should be Attainable by Solo Play: I know that many people hate the fact that most game content can be soloed today, but that's the nature of the beast. To that end, restricting certain recipes to raid drops is dumb, dumb, dumb. If you want to force the players to grind out faction favor, I can understand that for really good recipes.
