I know there's been many posts about this, but can't seem to find the right thread to ease my mind. I am playing quad boxing (newly started several weeks ago)

I am interested in warlock but not sure if i should go for 4 locks or 3 locks +1 healer (priest or paly?) Been reading but just need more clarity ;-P

If I am to play 3L +1Priest , should the priest be main ? I know it might be up to my play style but any expert could shed some light will be greatly appreciated.

Thanks bunches in advance.
