What about nerfing warlocks? Warlocks are more overpowered than all 3 of those classes put together. half a party of warlocks will kill everything before the other half has a chance to beat one down one trashmob on EE.
Since that is the newest class and benchmark, nothing here is overpowered, by comparison very very underpowered and the other prementioned melee classes are underpowered compared to warlock. If everyone is so overpowered, i'd expect not to see EN or EH on half of the LFMs.
