-Free For All Battles: instead of trying to make the 'swap team mid combat' suggestion, just make it so everyone can hurt/help everyone in a battle, i.e., you can use any skill on anyone on the field. Friend gets caught in your Sear? Call it a collateral. Because truly, fire doesn't give a damn who you are. Fortune Wind someone, and make them think you want them to live; use it a second time, and make the winds tear them and anyone near them to shreds. I see this as a good way to make betrayal battle RP.

-Local World Battles: Have the option to make any battles occurring in a local map (Cellsvich, Dormeho, Tannis, etc) act like a Black Beast battle. You would be fighting in the area you began the attack in, and that could give some realism to the scene, rather than acting tough in the middle of a pier in Dormeho, and then finding yourself fighting in a grassy plain. The only problem I can see with this is the normal Black Beast stuff, such as people getting stuck in odd places like the middle of the water, or one of the standalone islands in Chaturanga.

-Scale any Event made battles to highest player level, if in a party.

-Have battles matter. If Dormeho/Tannis/Coastal Cove were to not be defended multiple times from Black Beasts (or other, possible future attacks) it may look worse for wear. Prices may go up, since merchants don't travel there. The buildings may retain irreparable scars or defacing, and be boarded up or abandoned.

-Sea monster/Kraboid swarm attacks in Coastal Cove instead of Black Beasts every once in a while?

-Traveling merchants. Could be a pirate/sailor one that parks in Coastal Cove/Dormeho from time to time, maybe.
