Well that sort of is the plan - I must admit though that I dislike the feral S3 changes - the bonus healing from S2 was a nice touch and has been completely removed and replaced with combat stats in S3
I'll get the S2 leggings when S3 comes out as like you say they'll be cheaper. That will give me the +15% movement boost which will be cool as it stacks with the Feral Swiftness talent
