I want to suggest Pve only battle mount. With the end game dngs being so long without way points it can be a hinderance when you die to run all the way back to the boss without the move speed of a mount. Though, its only 75-90% it still helps a lot. The mounts could be disabled in the Battlefield so that issue could be resolved. This could also give a refresh feeling in some people who have a burnout from the long dngs. The mounts them self could be different from the disabled Battle mount in the server we have currently that were turned into normal mounts.
