So for my 300t fleet i get like 0.02% of my fleet for the raid?... no the raid wasn't right... I should have gotten more
You don't raid a fixed percent. This is what makes feeding so hard and that's why we could remove the feeding rule.
The cost of the fleets you bring in to raid the base is used to determine how much you can raid. If you bring a probe with 1 space and no weapons, you just destroy stuff on the base but don't actually raid anything because your ship is too small and can't carry that much. The more expensive ships you use, the more you will get. If you use cheap swarmers to power up, it won't work, you'll destroy a lot but capture little.
What you need to use is big and expensive main ships. You will want to use many of them, possibly even raid players at 80% of your power to get the most benefit. So this basically means, if you want to get full raid benefit, raid players under your power, not over it, or maybe if you have some tiny man ships on hand...
Experiment and see what's the best option. Cheap ships that have lots of power are no good for raids anymore. Feeding can get very expensive too.
God Speed!
