The guide Beckoning mentioned is
this one, and it's great! I can't wait to use it for my Druid, and to add all the spots in it to the
Per-Level Hunting Guide.
As for the ring, I'm with Daldaen: it makes more of a difference than buying an equivalent amount of gear IF you are charming ... which you really should be if you are soloing.
My Druid is only 24, but so far I've gotten way faster XP with charming than with rotting. It's not completely downtime free, but because it uses about the same amount of mana to kill two mobs:
- charm: 120
- 2x snare: 30
- nuke: 70
- maybe a heal if first charm gets resisted: 60
- ----------------------
- 280
as it takes to kill one by root/rot:
- 2x root: 60
- 2x crud DoT: 200
- 2x flame lick: 20
- ----------------------
- 280
it certainly means
less time spent meditating (not to mention less time actually spent killing the mobs).
