Okay, time for initial impressions.
Wolf only so far. Base stats are 16str/14dex/14con.
Going only wolf and no buffing is a bad choice. While I do gain +1 to hit from str, the AC isn't that impressive at 15. The trip attack is nice though. Running on Hard means that most trips fail.
With buffs? Yes. Very much yes.
Throwing on Barkskin for +2AC, Mage armor for +4AC, Cat's Grace for +2 AC, sacred shield for +2AC helps a lot, boosting AC to 24 (-1 for Enlarge Person). This is needed for running around like a cat with mustard up the unmentionables.
Wolf also gets a Trip attack.
Next, boosting that trip. +2 from wolf form, Bull strength for +4, Enlarge Person (base type doesn't change, so Enlarge animal doesn't work but person does). Now strength is at 24 with a +7 mod. The trips work pretty well now. Charge onto a caster and boom he starts going down like a hellevator in Terraria. The usual stuff (Bless, Aid, etc) is also useful.
All that strength also gives me an excellent to hit, more than making up for the 3/4 BAB (or for balancing out Power Attack). Damage is great (18-25), though the lack of sneak attack hurts since I wanted to reach that wildshape early. The lack of an Arcane Trickster for Divine Casters also sucks here. But the damage is comparable to Amiri with 3brb/2rog sneak attacking and the to hit is slightly better.
All in all it works pretty well, though it should be noted that all that battlefield movement requires a decent mobility score. I'm using wolf more than Amiri now for charging and running around on the field.
Other things.
Greater Magic Fang will help further with to hit.
Enlarge Person doesn't actually change the size of the wolf, though the stats are boosted and the reach is improved. The effect will also disappear if used *before* the wildshaping.
It requires several spells to work (mage armor, sacred shield, bull strength and cat grace, Greater Magic Fang, Enlarge Person). Fortunately there are several tiers that suck for divine casting, so it shouldn't be difficult to find the slots. It also requires an arcane caster for some of those.
All in all, it works. I haven't seen the Wild property on any equipment, so I'm guessing it will become less useful later down the line, but at least at lvl4-5 it works. And it's pretty fun to have Miasma as well as a Blight Druid since it actually sees a lot of use this way.
