I saw some players hanging around with kind of 12 druid / 6 barb and 2 WK or FVS or whatever.
The baseline for this build is druid 8 (Dire Bear) / barbarian 5 (T5 Frenzied Berkserker) / Favored Soul 1 (Divine Will). That leaves 6 levels to tweak things.
- More druid: up to level 7 spells, level 12 core enhancements
- More barbarian: level 6 core enhancements (e.g., Frenzy), extra damage reduction, Greater Rage (while Raged extra +2 STR & CON, +10 Melee Power, +10 PRR in medium armor).
- More Favored Soul: more spells, access to more enhancements (like Haste Boost and Close Wounds SLA), level 6 deity feat (e.g., Blessing of Silvanus for +2 crit range with mauls).
You could do druid 8 / barbarian 12 but you'll have to pick up a Battle Trance elsewhere (i.e., Falconry or Harper Agent). I don't think any of the barb 12 enhancements are worth giving up Divine Will, but YMMV. The minimum druid 12 / barb 5 combos have the option of combining A True Hunter with Critical Rage (+2 crit range +1 crit multiplier), which might be better for certain weapons than Focused Wrath.
The other thing this build has going for it: the Strikethrough bonuses from Frenzied Berserker carry over to bear form and stack with Natural Fighting bonuses. The downside is you need to take the THF feat chain to "unlock" those FB enhancements, even though the THF feats by themselves do nothing for bear form, so that makes this an extra-feat-starved build (unless you decide to splash fighter instead of FvS).
The warlock splash option is for using Eldritch Aura to proc
Arcane Warrior for +20 MP when fully stacked. Since the aura has 5-second cooldown between ticks, it's a minimum of 100 seconds to fully charge Arcane Warrior. And as with druid 8 / barb 12, you'll need an alternative Battle Trance from elsewhere.
Finally, remember you can't cast spells while Raged unless you have either Beast Awakened (Nature's Protector), Empowered by Nature (Wildhunt Shifter), or Draconic Rage (Draconic Incarnation). [Destruction domain only applies to cleric spells.]
