I've read a lot about how to solo as a druid on these boards, from kiting to root/rot. One method I don't see much about is using our animal charm spells. (and I do NOT mean dire charm...I thought about getting it but decided its worthless due to the level cap)
Here is a method of soloing that gives you much faster xp than any other kind of soloing for a druid, especially with the release of TSS. For levels 52-62 Druids should live in Blackfeather Roost. The level 52 charm, Call of Karana, lets you charm up to level 53. All of the Mountain Pumas and Mountain Snakes in BFR are charmable with this spell. Just snare, lower magic resist (at 53 you get glamour of tunare), and charm. Buff with Savage spirit, and pick a target. DoTs are optional, but don't heal the pet. Let its life dwindle away. Your pet should win the battle, and be low on life. Break charm (I used invis vs animals, low casting time/low mana) and finish your pet. You just soloed 2 mobs in the time it would have taken to kill one in any other method, and have most of your mana left over.
If your pet is gonna die, ALWAYS drop charm before it does...and finish it off yourself for the xp. Its simple enough to root any agroed mobs while you find another pet.
At 63, you get Command of Tunare, and can charm up to level 60. You can still fight in BFR, but you will get better xp if you go to the steppes. In the Steppes, you can charm ALL of the crowned mambas near the zone to Gorukar Mesa. 2/3s of the Timber lizards near zone to mesa are charmable (some are level 61). Use them to kill spiders with the same method you used in BFR.
It takes some practice, but you can level to the mid 60s VERY fast with this method. It slows down a lot in the upper sixties cause you don't get another charm until 70, and it only charms up to level 65. At 71 you get a charm up to level 73, so at that point things look up again.
