I got the Mida a long time ago during the raid, it made me fall in love with Scout rifles almost immediately. I used it lots however as you start getting more exotics you realize it not as useful as most. I barely use it anymore as I have so many other great exotics in the Special and Heavy weapons slots that out play the Mida. I would save the coins for something else as I think you will end up storing the Mida away in your Vault like so many other people.
