Character Groups and associated Cecil's Tasks

You only need to send 1 character per group to complete the daily tasks. Since the tasks are random for each player I'm planning to send everyone I can to earn event currency regardless of daily tasks. If their group comes up and I don't have anyone free, I plan to cancel one character as each group has at least one player that comes with a building. Getting tired so not sure if that wording makes sense.... basically I'll store one character from their building so it doesn't affect those already on task at Monsarno and if that group never comes up for a daily task then I'm already earning event currency instead of keeping one open and waiting for nothing.
