This simply isn't true, just do what all other destro players do. Make a WL and see for yourself, I bet you'll end up like the rest of them and stop playing it once you know what it's actually like.
Last time devs did an overhaul of WL it turned into a really gimpy version of mara with less dps, less surv and less utility. I don't think the people working on the WL changes had ever even played WL.
I played mara on live and personally I wouldn't mind a 100% mirror but after the last attempt i'm pretty certain that the devs will never do a 100% mirror anyway. All you have to do is either run with teammates OR get enough surv to endure the initial burst because there's nothing after that. WL has shitty dps and can't keep the pressure up, dying when running solo in full merc and full offensive renown spec is not an excuse to destroy a class.
