I'm going to agree with this one, as level 65 needed 31k; the multiplier seems a bit heavy.

Let me ask this question in relation: How long would you expect a player to spend completing the non-team portion of the bounty? With 31k, it took me between 1.5 and 2 hours to do it, and that's with ships that have a crystal capacity of around 2,000. I know my ships are usually configured a little more on the defensive side, but a good balance should be taken into account. As for the timing expectations, I would expect 30-45 minutes, no more than an hour.
