Ok so I went half orc druid for the 30 strength at level 5.
I played with the fire swords first time round with a wisdom build but then re rolled as a strength build.
Wisdom for flame swords ( yeah ok but bit boring )
Strength for all other weapons ( more options )
Cast your rams might, natural weapons buff, and your away laughing.
The only problem with druids seems to be the low BaB.
The form takes care of its own damage but works very well with the strength bonuses.
So I was thinking, grab 12 druid for the 3rd animal form, then splash 8 levels of whatever you want.
You could make some very interesting builds with the melee/tank animal form.
Low wisdom and a +3 tome
High strength, con and a reasonable dex. ( wolf gets bonus to reflex but - to will saves )
With the sonic roar enhancement thingy, your uber fast attack speed and ok damage, pets and heals , you are a one man wrecking ball.
Elemental forms sure if your a wisdom based toon, but it seems unless you are, or want the higher level spells.... why bother.
12 druid + your splash, half orc max strength, level ups in strength, take all your feats and stunning blow, improved sheilds, improved sunder... etc etc.
