In fairness, an Atlas isn't meant to use one anyways. No amount of engine is going to make an Atlas fast, and even with the biggest XL, you'd still have enough armor and pod space to be equivalent to the launch weight of an entire smaller mech, so it's a stupid example. Assaults in general over 80 tons don't use XLs because they get basically Jack-F-All out of them and they take up torso pod space meant for the big guns. Going 5kph faster isn't worth losing out on that Heavy Gauss Rifle or LB20.
Anything UNDER 80 tons however IS very much dependant on playstyle for IS XL survivability, just for the fact they can actually run. And most of the Chassis that get @#$% on for being XL-unfriendly (And just @#$% on general) in that range usually are because of incompetent pilots who either try to turret snipe with them, or brawl with them (Said mechs are actually meant to be used as mobile mid-range skirmishers/flankers, I.E. the Vindicator and Thanatos).
And it goes without saying Lights dying to XL hits is 90% the fault of the pilot, because they stopped moving. And if you stop moving when you're piloting a light, you shouldn't be piloting a light. Except maybe an Urbanmech, but the Trashcan is a special exception, what with being a Light mech that thinks it's an Assault, and somehow manages to tank like a Heavy.
