Well, I don't think you need exactly 5 supporters, 6 repair and 4 channel while others are just attacking. It's important to have your strongest union members on the front line. Everyone else should be helping channel/barrage and sometimes repair. If one of your main attackers dies, he should repair his base himself. It depends on his SP. Then you need 2-3 summoners because of the long cooldown after you summoned. One of your union members should give instructions (mostly summoner). Teamwork is the best way to win. The instructor need to pay attention to the enemy and should think of your unions next step. As already said, bahamut is good but it takes too long to summon him. Make sure, your orland attack buff is always active and try to attack your enemy as fast as you can so they can't heal themselves with Lorelei for example.

Maps are also one of the most important things for your summons. For example: Floating city, make sure to barrage your enemies bases because it costs 3 SP. (don't barrage if it costs 7 SP because you need to spend your SP as good as you can)

I hope I could help you a bit.
