Short post here: i love the hyperion but its more or less unfieldable.
Its unfieldable because it has a deployment cost of 30, and eats 45 maintenance per month. It has a cargo bay of 10 and eats like a capital.
I think its flux stats are fine. If you stabailize the shields you have 280/196 base which is better than all other frigates save the tempest. Plus, you know, it teleports. I even think its deployment point cost is reasonable. The ability to teleport on the battlefield and put phase lance or reaper fire down is pretty ridiculous.
What isnt reasonable is the costs associated with flying it. If i have to pay like a capital then i need to be able to support a capital financially in order to make use of it.
My solution is then to, rather than have increased maintenance it has increased deployment points. It would have a logistic profile of 6 or 8 or 10. Similar to other high tech cruisers. And only cost 6 or 8 or 10 to recover from a battle... but it would cost 24 to 30 DP to deploy. (You could also do this be reducing maintenance/deployment cost but it works better thematically the other way around)
That way its reasonable to field it but it doesnt dominate the battlefield by being able to deploy more than has the right power.
In game justification could be that the prototype is burdened not by being a protoype and so unfinished in terms of supply logistics. But that its saddled with a whole bunch of command and performance monitoring software which is proprietary and integral to the communications system. When you field it you have to sift through all of the preferformance data its beaming to your command module in order to actually get the important data you need and want. Thus its larger command profile makes it harder to deploy.
