This playtest has been one of the most controversial and critical. While I am usually one of the more critical posters during playtests, this time I feel I need to hand out some praise.
The Samurai is the best of the 3 playtest offerings mechanically. If left as is for the final release it would be just fine. There may be room for tweaking, but not much.
Oh, I do have an issue with this being an "alternate class" when it is just an archetype and two new orders bundled together with oriental wrapping and called Samurai, but mechanically it is outstanding. Truly one of the best out of the gate playtest offerings I've seen.
Kudos!
