2 captains in a 6 man are pretty good. With that situation, it's usually easy to go without a mini or an rk main healer. If you also have a mini or an rk, it's still a good group. Although it won't have as much dps as a group with a dps class in place of one cappy, the group will be more robust to various troubles you come across.
Also, you always* will find room for 2 captains in a raid.
*exceptions to everything, yada yada

Undo the U12 class changes. The trait trees were, are, and will always be a bad idea.
