Why do you construct scenarios that don't exist in game play? They prove nothing.
Its the best we can do to show power at specific, replicatable scenarios. You can't take a random battle as evidence as there are other factors in play, for example if the enemy facing the JLI they have even more of an advantage because that unit will be sniped even quicker...
We've all played against them. They are monsters. Even shock troops are unable to beat them if they have to close on them first and having sprint and camo JLI get to dictate the terms of their engagement (for a whooping 250mp)
Then there Is building spawning on top of that....
