If you know what you are doing with your own class then you don't need to worry about rogues. I do pvp with a great weapon fighter and the last domination I was in took a wizard and 2 rogues to take me out and I'm only lvl 35.
You are looking at me and I just behind a chair do you still know where I'm at? Yes exactly. It's called stealth not invisibility for a reason. Understand the true D&D rules and game play and you will know why you become like a shadow and not completely invisible.
