Mage against WarlockFollow

a relatively easy way to beat any druid while arcane spec this is
is to put slow on them imidiatly and they will switch forms to get out of it
once they switch back put slow on them again while mixing instant casts in to lower their health
they will constantly be switching forms to avoid the snare and will eventually run out of mana by constantly switching forms
the slow will give you time to stop their big heals with improved counter spell and just unload with PoM fire ball with arcane power a fire blast and AM and bam dead druid
