I am very happy with the Playtest, as are my players. The simple fact of getting to play around with new rules is refreshing and also seeing Paizo tweak things here and there is interesting.
The final game will be improved as a result, but more importantly, I am sure that when 2e does role out officially a lot of the more controversial decisions will be smoothed out. We will decide then if we play it or not.
The best part of it: it's not costing us anything!
So if you are not enjoying the playtest process, do yourself a favor and step away.
