Battle Regimens could work, but they need to be redone almost completely. Having to enter a new combat mode, queue up attacks properly, confirm the right order, and then LEAVE the combat mode makes for very awkward and slow execution.

If anything, I would like to see something like the following done:

- Two combat modes, Battle Regimen mode and Skill Chain mode. When you enter combat, your last mode is picked automatically. Switching between the two should be instant and done with a keyboard or controller shortcut. There should be no other delay or penalty for entering one mode vs the other.
- Combatants in Skill Chain mode will create skillchains for additional physical/elemental damage automatically after using TP skills, and can magic burst with spells on skill chains. Same as FFXI. Can self-chain.
- Combatants in Battle Regimen mode will create status effects on monsters automatically after using any skills in rapid succession. No confirmation needed. No penalties. Nada. Can self-chain.

This way there's a choice for having your combos either do more damage, or give status effects.
