Glad they fixed or toned down the snow from alpha. It seems better in the beta. I still notice frame rate dips every now and then but it runs smoother and looks a bit better. The Strike mission, holy shit they increased the difficulty on that one.
Still think the character models when you run around the tower looks cheap and low rez. It looks like the lighting is off compared to when you are in the character creator tool. Also the low level armor looks boring, I need better carrot on a stick lookin loot. Which I haven't seen in the previews either. Hopefully end game armor will look more distinct and bad ass. Right now the only reason for me to level is to increase or open up abilities.
The new Venus map, is fun to play in, but I think it looks horrible. You can tell it's built with last gen in mind. Like the moon base map the best so far.
My overall impression hasn't changed much when I played the alpha, it will be fun to play and get when it comes out, but without knowing what end game content will look like, not sure how long it will hold my interest. I'm probably more excited for destiny 2 when they ditch last gen, and build it solely for current gen.
