And presuming they would release 1 class each 3 months ... it would mean that first 4 classes get aproximately 24 months of testing ... while last one will get 3 ...
Not exactly best situation. :-/
That assuming that Larian cares for us to test the classes. What are the unique features of other classes that haven't been already tested with previous classes? Unless Larian plans to introduce new unique homebrews with those classes, then there is really nothing to test. Revamped reaction come to mind, if such revamp is coming, but other then that I can't think of anything.
