Well in my opinion there are three high level solo druid builds out there. We'll review those first.
Build #1 The expensive straight dps build.
For the most part with this build you will max all your dps skills. Vines, swarm, strike and Storm. After that you'll be left with one more skill to max. The choice is yours but the best choices in my opinion are:
Shield of bark, helps reduce incoming physical damage which is the most common at high levels.
Natures touch for obvious reasons.
Natures Embrace for heals over time.
Stat wise you want as much focus as possible. Only enough vitality to survive. Around 2500+ hp with gear.
Other druid utility skills could be used but i don't think they would be as useful as the above.
Number one problem with the build... You'll chug more restos than a frat boy with a freshly tapped keg. Your sigils will only matter in between mobs, which you want to be minimal, and with no guaranteed heal you'll be forced into spamming restos, which is why Shield of Bark is my top pick. Less damage recieved. All in all if you choose this build be prepared to spam restos but should have a decent kill time.
Build #2 Roots
One of the popular druid builds at the moment. It involves having your roots at a high enough level to root the mobs you're fighting. 37 can root up to level 190 mobs I believe. After that max strike, vines and swarm. You'll have one more skill to max after that. My choice is natures touch of course. My excess points were put into bark. With DL boots and jewelry I easily got it to 20+.
Stat wise I'd suggest enough vit to get you 2500-3000 hp and the rest focus.
As far as combat goes start by rooting the mob then apply vines and swarm. Spam strike and hit roots the second it cools down. The mob will most likely reach you during cast time but when roots is applied just run right out of range and keep hitting strike while keeping vines and swarm on the mob. Rinse and repeat until mobs dead.
Problem with this build... Unfortunately can be low xp gain. I average 6% per combo with this build. It is a safe build but has that downside.
Build #3 Howling Winds
For some reason this build has been getting a bad rap by some on the forums but it is an extremely good leveling build. It's just somewhat over-shadowed by the current roots build but if you ask me, given the resources, can be the best high level solo druid build.
Skill wise max winds. That's your number one skill. If you have a good ring use it also. Lower the enemies attack as much as possible. The more attacks you dodge the less you have to heal. The main damage you'll be taking is from skill hits which you'll be able to heal because guess what... You dodge most of the attacks making natures touch that much easier to cast. After winds max vines, strike and storms touch for your dps. Some prefer swarm over storm but its whatever you prefer. You'll have one more skill to max after that and its up to you. I'll obviously recommend natures touch.
Stats, what makes the build work. Sacrifice some points in focus and vit and add them to dex. Dex increases defence which helps with your winds. My recommendation is 5 str, 200 dex, rest in focus, once again enough vit for 2500-3000 hp with gear. In order to maximize the efficiency of winds you need some defence. If you have earthstone gear that adds defence you might be able to lower your dex stat.
Now to talk gear in this build. If you use combos, and I recommend you do, you can actually consider a main hand totem as more potential dps. If you have the DL totem then this is in my opinion the best build given the fact that you now have decent auto attack damage without losing focus in your mainhand weapon. I'd also recommend you play test with a 150 lux axe offhand for added auto dps. You'd lose focus as opposed to the 150 focus lux offhand but might gain more auto attack dps which isn't bad with the attack speed bonus from combos.
Wow that ended up longer than I thought lol... Anyways all in all though, the druid is the slowest solo leveler. I've tried all the builds and aside from #1, which was way to expensive for my taste, I've not been able to find a stable build to get 8%+ per elixer. Good luck on your trials!!! But unfortunately don't look to high :/...
