And it's why not all player Like 4e and go back to 3.X or PF
4E's druid can looked like a Bird but can only fly 6sec/5min
4E's druid can looked like a Fish but worse swim skill and would be drowned in the water
4E's druid can looked like a Bear but it's Strength like a sheep.
4E's druid can looked like a Panther but sneak like Rhinoceros
It's not the wildshape but the skinchange. it works like illusion, seems cool but do nothing.
Yes, it's balance. but balance aren't everything in role playing game
Sigh
I wasnt talking about balance but simplicity. It was a very simple way of doing shapechange that didnt involve looking up stats in a book.
