I haven't had any trouble with them, could be lucky timing of course.

On a very petty note: This is the first time I've not thrown my support entirely behind one side of a battle (both flights are so appealing to me, I can't choose, the only matchup I'd have this problem with). When I'm opening up both Ice and Shadow's posts in quick succession, it drives home how very very very handy it is that Ice has the spreadsheet quicklink right there in the top menu. If I were going to ditch the impartiality, that would probably be the deciding factor in where I sent my dragons.
