Many have told me in the past not to complain when choosing to use a Necro as a roamer because it isn't a class suited for roaming.
Go play in the zergs they say, or use a roaming class.
Now I would like to give this advice back to roamers who don't like the mount.
Don't play your current class/build if you think it cannot dismount players reliably in this mount meta.
Adapt to the new Roaming requirements and use a class/build that can work well if you want to be a roamer that can dismount players.
