I agree having a shared loginserver would be nice if possible
[You must be logged in to view images. Log in or Register.] . As stated in this thread & elsewhere the rulesets of both servers (ffa vs. rotation) are enough to keep both maintaining a pop in the presence of one another.
In all fairness I played both and have had fun, but then again as a casual on both who hasn't raided on either at this time I have felt no effect of these rules.
