how has anything about the enemies changed since Y1? They haven't, you were never bound to any one weapon. You CHOSE to only use burn weapons.And i know if your secondary or heavy matches the current enemies shield you pull it out to remove it. Then MAYBE switch back to Primary. Having A burner made no difference on strategy in Y1 and not having a burn ih y2 means secondary and heavy will be used twice as much because if you hit an enemy with the wrong burn it will take a min regardless of its attack lvl.
