Yeah, there are a few things a lot of people are not enjoying about the beta - long cooldowns for grenades, weapons that don't do much. I haven't tried the Crucible stuff yet. I think this was more of a publicity ploy than really a true beta.. but you know its a cool way to start the game for those who have never played before. I'm sure the regular release version will be great and we will be able to gain certain abilities to make all of these things a non-issue!
