There is nothing wrong with ordering to chant equilibrium, it's an effective means of temporarily disabling an opponent and commonly used, by some more than others.

Indeed I think of all, it's most commonly used by sorcerors (Wil being the most recent case to spring to mind), to varying degrees of effect.

However, as stated in my previous post there is a very simple defence and that's even before the fact that you have to have eq to be able to chant eq.
