Wind Druid skill allocation question

[:1]I could use some advice from the Wind Druid experts here. I'm playing my first one ever (currently lvl 77) and am sorry I never did one before, he's quite fun to play and much stronger than I was expecting. The question is, where should my next skill points go? I've read a number of the guides here and they seem to offer fairly different opinions.

Here's the current skill allocation:

1 point in Oak Sage, Raven, Spirit Wolf, Dire Wolf, Grizzly, Arctic Blast.

20 points in Cyclone Armor, Twister, Tornado, Hurricane.

0 points in Shapeshift tree.

Current items give +15 to Elemental tree, +12 to Summon tree.

He probably won't get much past level 86-87 by the time this ladder ends, so I'll have around 13 points to play with. He's most likely going to be a strictly PvM MFer and Baal/key runner for the rest of his career and I prefer offense over defense as a playstyle. That which is already dead cannot harm me

Thanks in advance for any advice/opinions.|||With that amount of +skills more points into Dire Wolf for Grizzly hp isn't necessary, which just leaves Oak Sage and Grizzly itself. You can get decent damage from the bear but it's essentially insignificant compared to your merc and 'nados, so I'd just dump the rest in Oak.

A point in the Vines can also be handy. Don't expect it to be a meaningful during combat, but it can fill your HP/mana bulb pretty quickly afterwards.|||Like he said, either pump oak sage or get solar creeper with 1pt if you have mana issues and then pump oak sage, either way oak sage should be your dump|||Sounds like Oak is the plan then, as mana hasn't really been a problem. Thanks guys.
