I still don't believe that's true. It was already said the demo was a recent build, but not of the final product. There's also the fact that people keep forgetting about demos is how they're a small bit of code ripped from the larger, complete piece. If anyone knows coding, messing with anything can cause unwelcome problems elsewhere. Even then, half the gltiches are cosmetic and have no effect on the game. About the only annoying one is "Flight Mode." There also taking feedback, so we can only hope they address the things worth address (game breakers and framerate).
And you know what? I can't consistently do the Trinity SSSmash. The enemies just won't let me, it's gotten to the point where it seems you have to completely go out of your way to do it under a specific set of circumstances that doesn't happen unless you're lucky, or take the time to set it up, at which point I'd rather just play the game the way it was meant to be played. Of course, Trinity SSSmash can still happen, but...it's really not all that easy, and I'm moderately great at the demo
So the people who can do it are probably better, which to me makes their perception of "easy" a little skewed >_<
Although, because I've kept trying to do it, I've found the enemy AI somewhat ingenious. When you're fighting the Hell Knight surrounded by Stygians, the Stygians make it sure to constantly be on all sides of you and the Knight, so that when you pull out Arbiter, they're ready to try and catch you stuck in one of its longer attack animations.
