Firstly, don't use old bosses for new levels.
Second, some of the levels were just replica's of others.
The only actual new settings were last campaign map 3 and 4, whilst I hoped all of them would be.
I do like the allies, though it would be more of a challenge to obtain them.
For some reason I liked how energy used to be, but I didn't mind them changing it to entertain a bigger crowd =)
