I haven't joined into any alliances since the beginning of my leveling in the games. So the following experience can to some extent for the individuals. However, it is worthy your attention since it is all my first-hand experience. I will introduce them one by one.
In the area of Azeroth:
When you are in 1st to 20th rating, you will have your assigned quests done in the newbie areas in all kinds of alliances, such as the Elwynn Forest, Dun Morogh, and Azuremyst Isle. All the quests between 1 and 11 are not so difficult for your leveling to 12. And when you have come to 12th rating, you should bear in mind you now will have your professional quests and be sure to learn salvation.
When in the 12th to 20th rating, all human kinds will live in the wild lands, Mark Delaney in the Bloodmyst Isle and dwarfs in Lochmodan.
What I recommend to select is the Bloodmyst Isle. I will have my reasons as following, the west lands is in great demand of quests and there will be hardly quests if you get to 15th rating. Lochmodan is also in defect of quests, and besides there is a huge lake in the middle which will add to your difficulties when you are in the way to fulfill your quests. However, things will never be the same in the Bloodmyst Isle, which is centralized in the centralized in the Bloodmyst sentry and the vindicator mausoleum. The mainstream quests in the Bloodmyst sentry mainly lie in the 2 places. Since all these quests have their respective allusion and hint, NPC can find them easily. What is noteworthy is that since there are no other quests in Bloodmyst Isle for other races, you will not receive the quests from the Capital. Therefore, all races can not go up to 19th rating except Mark Delaney who is privileged to upgrade to 19th rating. It is surely the better choice to have quests in the Bloodmyst Isle in the very beginning. You will just need FS, or SS to open the door for you. When all the quests have been settled, and you have your rating up to 20th, you can leave the base land of the alliances.
In addition, if you have enough time, you can have the Defias Brotherhood's series of quests done in the west lands. And the final reward for you is pretty good, that's a blue cloth. Detecting Undead will also require your presence in the west lands since it is so professional. What's more, one double jack will be needed if you are fulfilling your quests.¡¡
