Well From a druids perspective i can say initially i'm skeptical about the beast shape but I'll give it a run through to see how things go.
This will mean a major downgrade for my low strenght low con Druid. But the playtest will be the key to seeing if i'll wildshape again :)
Initial thoughts
I like that the new system will streamline play. Currently I have ten or more Wildshapes built on a seperate sheet. So the idea of being able to more quickly change into an animal is a good step.
There is a question I would put on the table about the wording of the Beast Shape spells. Currenlty a Medium creature gets stat enhancments and non land based speed adjustments only. While Beast SHape 2 allows for Pounce and other special attacks. Does this imply that if i have access to Beast shape 2 that my Medium shapes still do not have special attacks/abilities?
One of my favorite forms the Cheetah is a medium creature and has some wild land based speed and Sprint ability.
I'm a little surprised no Con modifier at all is given. My Animal companion is a much better tiger than i could ever be :) So if some Orc chops down my 60hp level 9 druid in tiger form. He would say that was the sickest tiger he's ever seen hehe.
But on a final note, if i could remake my Druid i would definately focus on Strenght and Con in order to take full advantage of the bonus's given through wildshapeing. This allows for two types of druids, the Wildshaper and the Caster. I'm interested to see how that would play out.
I'll let you guys know how the Playtest this weekend goes.
