well there are just 5 melee dps:
warrior = middle class dps with medium survivability
paladin = insane dps with high survivability
cleric = high dps with low survivability
scout = well actually i didnt see melee dps scout this patch yet but i assume its crap dps but with high survivability cuz it can be a tank
warden = high dps with high survivability (here is pure "melee" not optimal but in combination with caster even stronger so try hybrid if you want to be a melee warden)
ofc this is all just my personal opinion and i dont want ppl to be offendet by my comment...
