the thread i pointed out is just the discussion thread, and it includes tips but not many spoilers. you might want to PM romeothemonk as he seems to have played all the conquests extensively and could probably tell you all the differences that effect gameplay without spoiling you
I have not played RoR in the 1.22f patch (and only 1 or 2 times in the 1.12b patch) so i'm really no help. sorry.
