(Not routes, sorry)
- Start a couple of months late, after most people have hit 60 already.
- For Alts: Go to your desired AoE location. If it's open, grind. If someone is already farming it, log out and try again later.
- Play hardcore at launch and use the alternative spots if you have to--just keep grinding.
- Play super hardcore, don't sleep, get ahead and stay ahead of "the pack" to have the best spots to yourself.
If the last 2 options sound good to you, consider joining a Week 1 Molten Core guild, such as Divergence (NA Horde PvP - Faerlina).
