For era 6, there's no reason to put Tachis on the team--not only are they severely handicapped there, remember, they're slow to repair and consume a lot of resources if they get damaged. Only put one high-level Ootachi on the team when you're doing map 6-4 (he'll be dead weight until you get to the boss node, which suddenly turns into an outdoor day battle.)

I'm preparing for my first Regiment Battle event by reading the comments on last year's Regiment Battle. It seems that some people _were_ able to assemble a single team (including one ootachi and one tachi) that could survive both day and night battles, although naturally people got better results on the night battles if they switched to a specialized team of tantous/wakis/uchis.

I know this year's event won't be exactly the same as last year's, but I'm intrigued by the strategy of running E4 with just two teams--one all-purpose team to slog through the first day-night-day series of changes, and then a second, specialized team to finish strong on the final night battle, where you needed an A or B victory to have a chance at getting the special reward sword.
