It's... so so. I think it needs improvement.

It feels weird, rushed and slow at the same time.

There's a big rush on everyone queuing commands as fast as possible so the regimen can be initiated because of having to stop to setup the regimen is effectively stopping the flow of combat and many times players are called out for being to slow to add to the queue. It can be stressful.

I simply believe it needs tweaked or reworked some.
