Let me start with corruption: for what you can do, it's waaayyy to cheap to buy. You can destroy buildings on a planet while you have it corrupted, bribe your way past it, and other things. It cost roughly 2,000, including the cost of a defiler and for the cost of corruption. There are different types of corruption. But, it cost roughly 1,500 to uncorrupt your planet, and considering only certain heroes can do it, it's really annoying.
The starviper squadrons are very overpowered, and the whole constortion (not going to bother trying to spell it


If you do manage to get the 2nd death star and executor in the battle at the same time, you could be guranteed victory. The death star has a very powerfull energy blast that is so powerfull it can destroy a level 5 station in one shot. It reloads approximatley every 30 seconds, so you can imagine how quickly capital ships can go

Darktroopers are pretty good, so are the new rancor units for the constortion.
I really hope for a clone wars expansion, or even another one for that matter. It really could happen. BTW, they have a list of balance issues at the petroglph forums, and a patch with an updated map editor on the way.
