I'm not sure if they are keeping the tradition of Conquest + GL combo
But the next Road Ahead is on June, and CG was aware of the complaints of releasing a GL + Conquest combo with the Conquest character not being released before the GL was out (LV without Maul complaints where CG said to just be patient and wait till Maul comes out in ~2 months to see how LV really does)
So assuming RA in June, with the same release schedule, we should have two conquest characters fully released before both GLs are out, so we will have Conquest characters unlocked before the GLs
But I still don't think this is the case here, and Malgus is not a supporting character for a GL down the line mostly because they would've done a LS Conquest character first, then Malgus
