I loved the beta and never really went into it with super high expectations like some. I mainly wanted it to be more fun than Borderlands was, and it succeeded very much so in doing that for me. For me the only way the game will disappoint in anyway is I will want more of it than it can give.
It was like that in the beta as well. It didn't matter if you were level 8 or level 1 the level 2's did the same amount of damage to you. Guess they want it this way so you never feel like a god? Kinda destroys the feeling of becoming more powerful though in a way.
I very small hint. I definitely wouldn't hype myself to thinking graphics will be that good this generation. I'd say Halo 5 may look slightly better than Destiny.
