I hope that there are going to be many more options in the Arena. Examples:
1. More types of AI (basic is not enough).
2. Custom selection of skills and abilities for each Team.
3. More types of match: deathmatch and kill the king are not enough. Ideas can range from classic multiplayer (flags) to kill the boss (huge creature), waves of enemies, co-op against monsters….
4. More maps of course, but more importantly custom maps.
5. Ability to play as monsters.
6. Treasure maps where you try to find treasures while the other team is trying to kill you.
In short, we need to have the option to fight epic battles. As it is now, it is quite simplistic….
