I didn't get my rogue epic til 52 (last winter sometime) and quested it myself and had some help from my guild for the final fight (and the Steamfont part). I'd argue then though that there were less MQers than there are now.
You don't need it til the later levels...I had a few comments in CoM about not having it, and nobody really complained in KC, but when you get to Sebilis people will start to get shitty about it because the min max crowd all seem to hate leveling by then and a slow camp clear rate irritates them.
Til then, if you've got 5k or so... grab a Rapier of Oriin, and a 0.5 ratio off hander (Jade Mace, Blood Point, etc) and your dps won't be bad at all.
How far along are you with your epic? Have you done the Neriak/Kaladim letter stealing parts yet? Skillup your pickpocketing for those to minimize frustration, and screenshot/post here the MQers who give no shits about jumping in ahead of you when the mobs repop
