that 2 second pause will defeat the essence of having Initiative i think .. The delays between the two players is also the key thing here also and the other is the perfect timing of the player for using/activating their skills .. just like when we are fight against someone with interrupt ninja like iruka and samui, we wait till our barrier ninjas turn to move before we use the barrier skill so that the opponent cannot interrupt us .. that are the some factors i guess when it comes to that issue ..
