people have been raiding just fine through T5, T6, T7 (with T5/6 pre-pvp, still people have raided that after kosrelease) with a split class set, why do you suddenly want rangers running around freeport?
i think it ruins the immersion and idea of war between good and evil to have all classes on both sides
are you wanting this because you cant succesfully raid T8?
or
because of a lack of population (exile having their own sacred blue-server)?
