I'm still not happy with the Sym Rework (AGAIN) but the role lock honestly changes how she plays. Having two tanks constantly makes her way more viable now.
Still the TP needs to be reverted back, her constant TP-ing around was so much fun. But I can see that can get oppressive in the new 2-2-2 role lock. Because let's admit it, she is OP when you have a competent shield tank around. With the Role Q, her survivability should not matter as much since it seems like the devs want her to be around her tanks constantly anyway.
I also moonlight as a flex player when I'm not playing Sym so the role-lock is awesome to me.
