Well technically if we fight you, we would definitely lose because of your advantage in stats, if we want to upgrade, then you will have to be patient and wait, but it takes a long time to do that. However, if you downgrade, you would have levelled the playing field and can actually battle, instead of complaining, "Oh! You guys are so weak!"
So you want to battle us, as you keep complaining that we are too weak, well evict your crews, and replace them with T3 and T2 crew which would take about 1 and 1/2 hour. However, if you want ask to upgrade, it makes take months to reach your stats and by the time we reached it, we totally forget about this whole dramatic argument. So want to fight? Make it fair instead of having your T4 and T5 crews making it nearly impossible to battle you!
