Don't know if this topic is still going, but I usually always play IMPS, and Build about 5 or so ISD2's, with about 30 or 40 TIE's (Mixed types). BUt, whenever I build and start attacking in OFFLINE FACILITIES mode, the rebels always just send a raid of fights and are MAYBE backed up with frigates and gunships'boats. I never get some awesome battles with destoryers, AKA Mon Cal's... Though, when I play in the REINFORCEMENTS mode, the thing(s) they build mainly ARE the Mon Cal's... weird
