Beta Got Me To Cancel My Preorder.

Was thrilled to get the Destiny beta but after two days of play I have decided to delete it and cancel my pre-order of the game. The reason is simply that the play is too darn hard at Mission 5 The Last Array. I have done almost nothing all day but try to get by it. I just do not think it is fairly balanced and it has been the most annoying and repetitive few hours I have ever spent with a game. Truly, truly terrible designed. To accomplish Missions 1-4 in about three hours then epic fail in Mission 5 after more than six hours? Even after leveling one step higher than the mission? Maybe if I had someone for co-op play but I do this solitaire. Anyway, I know I am not in the top tier of players so I am sure many will love this. But not I! Can't wait to get my $5 back.
