There's truth to that about others leveling up too, but I'm Warfiend, dammit, not your common MW riffraff. :D I've been playing since last night, leveled up once, and got only two boxes and 1 warhead. This feels like the event before last to me where I only got one prop. I'm just personally not feeling it on this one.
The unit is great as are the incremental units, and I know loads of people here will do well getting at least them if not 10, but it's not feeling right for me. I'm good though, that's how these things go.
Absolute best of luck to everyone! Go Go Go! :D
