Traps are the way to make sure you have a chance at your better planets. I was thinking for planetary invasions, two possible improvements:

1) allow the stacking of traps. If you have one active on a planet, allow someone to stack the same trap type so it never wears off.
2) make the time longer, effect better? Not sure, but traps do give some reasonable protection for a planet...but just thinking that this may help give most planets that are important to people a chance to stay theirs for at least the 12 hours they are being attacked.

For ships, I am not commenting on this, I am sure others can give feedback, but the traps to me on ships seems just fine..

1 week isnt enough for you?

That was just an idea, I think 1 week is fine, was just throwing ideas out there for that really.

The big thing that I think would be nice was ability to stack traps.
