interesting one their, i found it depends on the tactic, the more free and expressive you allow your team to be the less you should use the OI , however it also depends on your team if your playing a better team OI's can help, unfortuanatly I cant seem to either create or find a tactic similar to the way the best team in the world play at the moment just take the barcelona principal of closing down your opponents with great speed and then playing unbelievable football, as a fellow gooner i wish i could recreate that tactic on here, but its way to complicated for me.
