So a more "user-friendly"
GSL is...
...good for
4E -- more
3PP support for
4E means more options for 4Eers; those loyal to a particular
3PP will be more likely to give
4E a chance;
...bad for 3.5E -- more
3PP creative effort will be put into
4E and, thus, probably less
3PP creative effort will be put into 3.5;
...mixed for PF -- with less
3PP support for 3.5 , some 3.5ers will drift towards PF (or
4E); those loyal to a particular
3PP that might otherwise support 3.5/PF but is now supporting
4E will be more likely to give
4E a chance.
Approximately right?
