Moth3r is probably annoyed at having to quote himself as a reminder to someone so soon after he originally said it.

Just helping out when Ric is not around.

As for the AT-ST, I kinda find it funny that there are people who didn't notice it. I've always found that, since they're shown so briefly, they stick out like a sore thumb. Before I saw ROTJ, I thought "wow, they have two-legged ones too?!" To that end, I'd hate to see them go in ESB:R, especially if Ady could smooth the animation a bit, but I can also understand why it would be taken out.

But seriously, where do y'alls think that the AT-ST is more impractical; Hoth or Endor? :p Tripping on logs and Ewoks, or tripping on chunks of ice and cracks in the ground? Sure they have big feet, but blimey, it must have some supercomputer that scans the ground around it all the time...
