When I was at Camp Slayer (BIAP) the latency was horrid (900-2200ms). I was barely able to keep one guy alive, much less be able to multibox. If you only ever have to deal with targeting an enemy at the beginning and not react quickly to additional mobs, you might be able to pull it off. But if you pull several or a runner pulls more to you, you are probably gonna have a corpse run or 3.
Casters are much easier to deal with on a high lat connection, due to you being able to press your button during the casting bar ahead of the finish of the previous spell. A rogue? I stopped playing mine while over there. Auto-attack is about the only thing that you will be able to do. Healing will be an issue too. You will have to anticipate the incoming dmg by a good couple seconds instead of reactively healing.


Good luck with your setup and stay safe.
