you can make the attack to initiate like the following:
select the attack (doh)
then use the old style targeting system to pinpoint your victim
now it will have the opponent locked. and will start to charge the attack the moment the victim was locked.
the view would auto center so it make´s it a litle easier to shoot straight at the opponent, when he jumps off the wall it would brake off the view.
when you start to charge you will have 3 points on which you can release the attack
1 ring
3 rings
and
5 rings
the first ring that shoots will go for the neck of the victim, the animation could have him grab the ring with 2 hands and he will start struggling it.
off course on people with equal level this 1 ring would only hold for one second. but it can be enough time to do some more damage
people who will have a difference of atleast 1/4 of the attackers pl would end up struggling 2/3 secs
the second way, the 3 rings will go for the neck and the 2 legs, the animation could have him trying to free his neck first and then grabbing both rings at the same time. the struggle would last at least 2/3 secs but if the difference is about a 1/4 lower than it will take up to 4 secs
the last option the fully charged attack would shoot 5 attacks.
gooing at neck feet and arms
this struggle animation could be a charge up of energy and on the verge of winning the struggle it would have a flash of ki engulfing the rings and freeing the victim.
this struggle would last for atleast 4 secs.
and could work up to 5 secs.
the way i see it
vegeta 2.000.000 pinpointing a 1.500.000 goku with 1 ring last 1,25 seconds
vegeta 2.000.000 pinpointing a 1.500.000 goku with 3 rings last 2,5 seconds
vegeta 2.000.000 pinpointing a 1.500.000 goku with 5 rings last 3,75 seconds
vegeta 2.000.000 pinpointing a 2.000.000 goku with 1 ring last 1 seconds
vegeta 2.000.000 pinpointing a 2.000.000 goku with 3 rings last 2 seconds
vegeta 2.000.000 pinpointing a 2.000.000 goku with 5 rings last 3 seconds
vegeta 2.000.000 pinpointing a 2.500.000 goku with 1 ring last 0,5 seconds
vegeta 2.000.000 pinpointing a 2.500.000 goku with 3 rings last 1,25 seconds
vegeta 2.000.000 pinpointing a 2.500.000 goku with 5 rings last 2 seconds
the charge would take 3 seconds to fully charge and it will work in a straight line. it would only work if people are stuck in a wall.
not if they are on the ground.
if a victim is hit by a ring, and he struggling with it the attacker can still charge up the four other rings. but he can not shoot more than 5 in 20 seconds to prevent it for abuse
the only way to initiate the attack is by locking someone that is stuck against the wall.
