With rebels you need to learn speed control. I did this by running dual ISD's and learning not to rush with them but to time their turns and use the Nav Command to the fullest. It takes a lot to do but it can be done.
This is such an important point. I ran a Rieekan squadron list for quite a while and enjoyed it. However, the real victory from this time, was that I am now at an absolute jerk to play against in the squadron battle with minimal squadrons.
I bring two YT2400's and two AWings. CNinja will testify to just how much disruption I can achieve with this motly crew. Against his triple Vic Rhymer Ball those four didnt succumb till round 5. On paper they shouldnt have lasted past turn 2, but I've learnt a lot of tricks.
Next up, triple MC30's with Jainas Light. If I can work out how to manouver those guys, the world will be my oyster.
