For someone who is reading the end of this thread, please do not listen to posters who claim JBB is only good for leveling from 45-52 or so. This is mathematically incorrect. Posters like Troxx who constantly claim otherwise have not leveled a Shaman from 45-60 with JBB.
https://www.project1999.com/forums/s...&postcount=523 - Here are some calculations for JBB vs. Root/Rotting.
In terms of leveling speed, these are the ranked options from 45-60. All options can include Fungi Tunic/Staff if you can afford them:
1. Epic + JBB + Blight, Hammer of the Scourge (if you are fighting 3+ mobs each pull).
2. Epic (if you are fighting 3+ mobs each pull).
3. JBB + Blight, Hammer of the Scourge (Every race that can use it, no Epic).
4. Root/Rotting without JBB or Epic.
If you can't afford both Epic and Torpor, Use JBB and save for Torpor. You can resell JBB, Fungi Tunic, etc. to get Torpor money. You can't resell Epic for Torpor money. It's better to have Torpor and no Epic at level 60, instead of Epic and no Torpor at level 60.
