Me and Anaryl thought up a way for people to use a few loopholes with a friend to get lots of credits and victories for a avatar. We tested this briefly, and it worked. This idea I game up with after something similar happening on the Aeon front unintentionally.
Step one: Get a friend on a different faction in Galactic War.
Step two. Have friend attack one of your planets that you have a >50% control over.
Step three: Have your friend immediately uncheck the 'Available for playing' box.
Step four: Defend your planet for a free win and credits.
If two people spend about 15 minutes uninterrupted, they could rank up as much as 20 times each, with max credits.
A longer way to do this is have a friend attack your planet, then recall as soon as you are in battle, but this takes longer and I'm assuming leaves a obvious replay evident trail.
I would like to see this fixed before the game goes out of alpha, It would defeat the purpose of having a high ranked avatar if you could just re-level one in about 10 minutes. I'm not sure about how you could go about fixing these, so if anyone has any ideas...
