I've never played a PvP server before. Does that mean rolling a healer isn't necessary? I'm not saying I'm going to roll a healer...but I was thinking about my smug being a healer.
Every class is very important despite the server rules. Can you imagine going to war without any medics on staff.
I guess that's why companions make it easier leveling. But still, I can so see myself getting attacked in the open...and it'll be difficult to defend myself as a healer...I'd have to concentrate on my companion and myself at the same time. I guess it might be a sharp learning curve...but I'm sure it'll be great in the end.
