Tried to 3-boxing shadow priests but at 20 lvl I have found out that mind flay removes follow and I dont really like that :P

Thinking about multiboxing (3 or 4 or 5 - not decided yet) balance druids. In boomkin form they've got alot of armor and one always can shapeshift to healer or bear and do the thing needed. What do u guys think about it?
