Well I'm not talking about bugs, if that's what you're talking about as pro mode does have them, but You see unfair, I see logic and challenge. What's the point in making pro mode EXACTLY like normal mode with some "added" things that don't really change the experience?
That was the whole point in making pro. It was to make the game change the way you play. It took what everyone did in normal mode and made you do something different thus giving you a fresh new game to play. Sure the challenges are crap to repeat, but do what kotti just did, a run with a specific weapon. That's what I love about pro.
But if we go through both modes, there's far more bigger issues with normal mode than pro mode. I guess it's just about perspective.
But here's a question. What if pro mode was what the game was when it was first released? Would many have issues with it? I don't know, because normal mode wouldn't have spoiled us with how everything was just so convenient.
