I think the warlock seriously needs a support class. The hunters have night stalker that can vanish their ally's and de buff their enemies defences. The defenders can increase their teams attack power or defensive capabilities. Warlocks can... Save them selves when they make a mistake? They have the 'song of flame' perk but it's not very noticeable and who would choose that? They should have a healing/support class. Or perhaps even have sunsingers re worked a little to be more balanced in pvp have have support utility in pve. It's a shame that no posts on LFG read 'we need a warlock' it's just Titan or hunter. Having a shaman class for the warlock that can create 'pools of light' (or something) that your teams mates can stand in to rapidly regenerate health or boost attack sounds cool.
