Could always try Unwritten Legends.

While it's not called 'equilibrium/balance', there is the roundtime system.
Most combat-related actions and some non-com actions incur varying amounts of RT, during which you can't do anything else that would incur it. You can still talk and emote though, which makes emoted combat possible.

It's also not the 'kill orc', wait ten minutes, combat. You type out each attack, aiming at body parts, or using special abilities or spells.

It's an RPI, so RP is in force at all times.

Unfortunately, the player base is still rather small, especially during weekdays. We go from 1-3 during the day, to up to 20 or so during peak hours. The world is small enough, with one capitol city (And a few others that people mostly go to for fancy clothing or weapons), that you can generally find anyone playing, but still go off and do your own thing if you want.

Don't be put off by the application process, I've never heard of anyone being rejected.

Unwritten.net would love to welcome you, I'm sure
