"Might seem cheap" = blocking a whole football goal with a bus? That seems like a whole different kind of cheap to me. Like a "why was that even allowed"-kind of cheap.
I mean, if they didn't wanna deal with that boring-ass Pudge+Chen combo, they coulda just banned Pudge, because Na'Vi is the only pro team to play him anyway. But nope, they just let Pudge through and faced #dotamechanics.
