I went with 5 rogues. Adding a healer seems like a LOT of extra work and keybinds + it`s hard to keep control on him because sometimes you want to him to stay in stealth and so and that takes some extra work. Going out of range and so.

My 5 rogues are currently only in lvl1 gear with 2 heirbloom weapons at 60 in the outlands but they die a lot without the gear haha.
