i think the network is a bit congested now thats why the high fees,. i dont know more about the issue you are facing
Consult https://bitcoinfees.21.co/ with network congestion if you want miners to prioritize your transaction. Tradeblock shows the average transaction size is 550 bytes or .00033 bitcoin. Round it up to .0004 and that is the minimum fee in bitcoin you should be using per transaction. You could use .0005 bitcoin per transaction to make it high priority.
It's not a fee problem, it's clearly an Armory issue.I'm thinking there may be a python error. Can you post the Armory logs? If they are too long to post, go to http://pastebin.com/ and make a new paste. Then post the link to that paste.
