I think for part III of phase 1 people should be able to comment/post feedback on decks not in element as long as the revised copy of the deck has at least 25% *insert element here* in it. Since a good master should understand other elements as well as his own, I think this would open up quite a bit of non double posting and give other elements that already have set in stone decks that people post over and over (earth ex = shrieker rush, fire = cremation etc.). As it stands some elements are limited to what they can post on/give feedback so you have a lot of people posting/commenting on the same deck really not giving feedback that hasn't already been stated.
I just think it would give everyone a little more options and how can you be a good master during war if you don't know your opponents weakness/strengths in his element O.o
