In 1.11 it's a dog-eat-dog world out there, so you better level up quickly. This quickest way that requires minimal glitch rushing and high level help is this:

• 1 to 6-7: Find full normal games to kill around in blood more and cold plains. I find that baal run games are great, plus its fun to have everyone party you. If you can find a slow moving party, i.e., a bunch of noobs, you can get more exp in before you need to change games.
• 7 to 15: Trist runs. Although it may be difficult to find a fast moving, full party game, keep searching, it pays off quickly. Avoid games with party members higher than 17 or 18, as they begin to suck up any experience you should be getting.
• 15 to 20: Tomb runs. This is usually easiest with a higher level character that can clear them quickly, while you leach some experience. Try to find games that have a high level killer and many party members. It usually only takes one game, since there are 7 tombs, if done right.
• 20 to 24: Norm cows. With a full game and a good leader, it usually only takes 2 or 3 games to get to 24. When you reach 24, you should get a rush to act 5 done if you hadn't already. This is where having friends comes in handy.
• 25 to 40+: Norm baal runs. With a high level, the experience comes very quickly. Keep going until you are at least 40, as that is the level required for nightmare anicents quest. If you don't have any friends on at the time, or don't have any friends, you may want to keep doing baal runs to pass the time. Another good way is to make or join "baal for quest" games, in which high levels will kill baal for you to get the character they are glitch rushing through to nightmare. Its common curtisy for them to rush you through nm as well, but some people don't do that. :/
• At least 40 to 60+: Same as the above, except you will be doing it in nightmare baal runs. Although you don't need to keep baaling in nightmare after level 60, its good to go to about 70 or so, as the experience is still good. If you don't have a rusher for hell, consider trying to offer your hellforge quest to a rusher. Don't scam them. It's not nice .
• At least 60 to 90+: Hell baal runs, make sure you get into runs with a strong teleporter, its not fun waiting a few minutes only to have the party leave while still in town. Meet friends during this time, it will help in the future to get into some baal runs.
• 90+: When doing baal runs, you may need the experience from baal, as that is where the majority of the experience comes from in the upper 90s. "Top 2" is a way of solving this, in which the highest 2 levels (or if an agreement is made, whichever 2 want to do it) will leave the original party and make their own. In this party they will kill baal. Usually, the top 2 people will offer baal's drops for the extra bit of experience.
  
  Good luck, and, when in high levels, have fun spending several all-day baal runs to gain a single level. Have fun with the extra 5 stats and 1 skill point. The glory will go the the people with the most patience.
