1) When do you get control of the protoss motherships? I did the Zeratul missions, and don't remember ever getting one. Maybe I just had the ability to build one, and didn't. I sort of massed void rays in that last mission.

2) You thought the battlecruiser was bad? I loved it. With no upgrades, it does about 40 damage per second, if I remember right. Fast firing (so you don't waste powerful shots on single guys and take forever to reload), hits air and ground, doesn't get caught on terrain, etc. What's not to like? To say nothing of the fact that with an armory upgrade, each cruiser can absorb an extra 400 damage at full energy. They are slow, and they do take a while to build, but 6 battlecruisers with two or three science vessels backing them up is an almost unstoppable combination. Then again, my only experience with them is on normal, and I'm not sure whether I'll have the time/cash to build them on Brutal.
