Yes, or if there was some way to target the one that you wanted.
Hell yes. Getting a certain piece of gear feels way more rewarding if you know it's the best you can get (for your particular difficulty level).
Don't care really. They don't add much, I wouldn't miss them if they disappeared.
Now that's just silly. The gear should still drop, but in one version only. I don't mind valor points as a complement for those slots where you got unlucky or for non raiders to still be able to get really good gear.
Cool events should still be part of the game, if they're random or not doesn't really matter but it's easier to plan out your time if you know when and where something is going to occur.
