I dont like how repairing works and I think fleets need to be changed. Trading coins for experience is worthless when I'm levels behind in ships and can't fit what's in the research tree.
the only complaint has to be the fact if a character is dead at the end of a battle they don't get xp. This makes you slowly fall behind to the point where your 5 levels behind the enemy and eazy mode makes it feel like everything is a boss in hard mode
Honestly the best feature in this game, is it auto scrolling with battle it does look like wander sometimes but you realize its staying centered with the battle for you.
What do you mean "it crashes"? It freezes up? It gives you an error of some sort maybe? You could always try playing in another browser see if it get rid of the problem too.
How do you think the repair system should be redesigned? And what do you think needs to be changed at Fleet Arena?
