As the benighted mongoose says, hex grids are far superior to Cartesian grids - philosophically, at least. I do miss the keypad movement; it allows much easier fine control and my mouse hand gets so tired.
I'm still undecided about the Designer. Now that I've discovered middle-button rotation, it's not the disaster I first thought. A couple of issues, though:
* Tool tips on the category tabs would be nice. As in, "Why the heck aren't they already there?"
* I understand why there are mirrored components, but do you have to mirror everything mounted on them? One weapon on a mc occupies two hardpoints. And it's difficult to tell which C are M.
* I do like the reciprocating animation, though not sure how useful it will be.
More as I use it more.
BTW, does anyone recall what a PITA the GCII designer was before you got used to it?
