I personally think RD-style battles are an interesting way to spice up the game. That being said, things I would change...
1. More rewards. Even if it's just doubling the amount of orbs in the tiers that get them or replacing the regular badges with orbs.
2. Give the 3rd place team a bonus multiplier ala the Voting Gauntlet. If 1st place is too far ahead, as in has more than the other two combined, give them a hurting modifier, 0.9x and down, decreasing if they still manage to stay too far ahead. 2nd place will either have a consistent 1x multiplier, or if too far behind 1st, a smaller modifier than 3rd but still helping.
3. This is more of an address to the RD system in general. A newly-spawned unit will have to wait a turn before being able to teleport.
4. As several have already said, increase the turn limit. Even 15 would help.
5. Nobody respawns, player or enemy. If the enemy brigade gets wiped out, you instantly win with full score (minus any unclaimed camps?). Likewise, if your brigade gets wiped out, you instantly lose.
6. As I despise Horse Emblem and have a brigade of mostly infantry and armours, penalize horse-heavy brigades in some fashion.
