In game? Woo hoo, badass enemies are more fun to fight than non-badass enemies.
We'll see how they handle the Invasion. And you should note that the Sphere Mechwarriors are fairly badass themselves (because if you're going to strap guys into five meter tall machines of death, you're going to want the best in there), so it won't be like going from fighting stormtroopers to Boba Fett, it'll be more like going from dueling your rival with revolvers to dueling your rival... while he's using an assault rifle. If you kill him, you might be able to get an assault rifle of your own if you grab decent salvage. Until then, however, you'd best hope that attrition or lucky shots get him before he gets you.
