Newbie smiter/famine to DoA (foundry)

I'm having issues figuring out where exactly to place myself to keep out of aggro in some of these rooms.. is there a guide or a map with a BIG X on it to show me where I should stand at?? My team and I are figuring out the 600 build but just keep aggroing a group here or there when they spawn new groups.. any help is appreciated.

should stand about 3/4 away of your compass from your allies, stand in corners in the first 3 rooms
