Right now, the most broken thing is All ranger because of current patch arrow storm you unlock in Act 2.
Then mages become the next one because meteor Shower and Hail storm. Those two spells are just weaker Arrow storm.
The problem with mages is that they kinda suck until source spell are unlocked (act 1). Before that, physical damage comp is way better due to the abundance of strong items and as long as you keep your weapon updated, they should deal insane damage at all time.
So if you want an easy life, just play 2 ranger + 1 support tank mage and and a warrior or another ranger. Focus fire enemies so hard they die before they act or round them up and let the 2H warrior do the wiping as 2H warrior will provide the most AoE damage when Arrow storm cannot be used.
