Footholds into enemy territories can be done as you grow in levels and should be completed before reaching Level 120. Take the time after completing your first zone to do your first foothold, or you can choose to complete one as soon as you gather your 100 War Resources which will prompt you to return to your mission table area where the first foothold quest can be obtained. Similar to how your initial zone selection was largely irrelevant, this selection is, as well. Simply pick one and complete it to earn your Mission Table second champion. Send your champions out on missions, recruit troops, and then head back out to quest in your second zone selection.
Profit is only created if you make sure your costs are less than your earnings. This is not so much an issue for gatherers who simply trade in some time and effort to gain their wares, but for production professions, this must be kept in mind. Many high-end items that sell well require materials that cannot be provided by the gathering profession normally paired with your production profession. To craft these items, purchasing the raw material from the AH or another player becomes necessary. You must keep record of how much you spent to obtain these materials, or else you may price the finished product inaccurately, either too low that you sell it at a loss, or too high that you can't sell it all.
Do quests and complete the story of your first chosen area before returning to your capital to scrap all of the equipment items you acquired. You should be around Level 113 by the time you complete your first area. Before selecting your second zone, head to your faction hub ship to acquire your introductory quests to the mission table and your champions. Complete this introduction and then pick up the quest to establish your first foothold in enemy territory.
Unable to tolerate Sylvanas' dishonorable tactics, Baine Bloodhoof turns against her and, with the help of Forsaken priest Arthur Zelling, smuggles Derek out of Horde territory with the intent of returning him to Jaina. While Derek is successfully returned to the Alliance, Baine's "treachery" is discovered by Sylvanas and her loyalists, resulting in Zelling being executed and Baine imprisoned.
Although the Battle Pet Trainer will only offer to teach you your race-specific companion, it is possible to add all of these pets to your collection. You can either find them in your faction’s auction house or you can create a character of the race whose pet you would like to learn. Using your new character, you can seek out any battle pet trainer in major cities. After you learn the pet, you can delete the character; the pet you learned will not be removed from your collection.
