This threat has really great infos, thank you all!

I just did my first boosting and I must say I am shocked - I did lvl 1-40 within 11 hours played.

Before I always just did Inis with the team at the same lvl, but that takes an order of magnitude longer. Of course you need to do this to learn multiboxing still at least once

I used my lvl 80 GS 4700 prot pally, toons were what is missing for my 10box: a holy paly and a lock. Accounts have RAF and both toons have 20% xp bonus from heirlooms.

Here is the sequence:
- Lvl 1-10: serial killing mobs at same level. in my experience faster than running around for quests
- lvl 10-20: deadmines. not a perfect place, but good for learning mass pulls
- lvl 20-30: stockade. perfect, easy to reach, only xp limit is the 5 inis/hr timer
- lvl 30-40: sm cathedral. here I started looting to stay in the ini timer
- lvl 40- now: started BRD, not so great - will check ZF

Not sure why Blizzard allows boosting, they could easily just turn off xp when you are grouped with someone more than 10 levels above you. If I remember correctly, EQ2 doesn'even allow grouping in that case.

They probably figured it keeps us going... Somehow I feel I have earned it
