Don't get me started... a 22,500 cruiser is nothing.
I constantly lose super hornet against someone one hundredth of my strength. Needless to say, super hornet is equally powerful as a 2 million dollars unit...
Chuck is right, devs keep changing the battle mechanics...
at a time, i won't lose units at all against puny players; later on the casualty went up drastically; then it went back to no loss... it repeats over and over.
you just need to catch up with dev's randomly alternating update.
