JUMP FORCE

( it's a copy paste of my solution in difficulty expert )

Hi, I had this realization earlier.

One thing to know is that you can get rank S on the same mission 10 times.

The simplest for me was the experience, this quest must be done several times to mount his characters of 70+ levels.

I managed to make the S fall by losing the least possible life

also finishing the 2nd round with a flash final in "awakening" mode

One way to reduce the life of the opponent is to start by typing with X and chain with a Kienzan or or meteor combination.

I used a lot of meteor combination.

Some I managed by doing a perfect in the first round.

use the support characters with LB (hold down).

Improve well your J-Skill use a G object. ( personally I always used the G-attack)

Also improve your support skills.

Stay a maximum on guard when your opponent can make his ultimate attack.

Avoid taking risks as long as he can do it.

In addition, do not smash from a certain level, the AI ​​becomes very strong with the fast dodge, even if you make a quick dodge, they come to counter you.

Observe the weak points and how the opponent attacks.

For example Black beard his ultimate attack if you are a little away from him, the black thing on the ground will not affect you and you will not suffer any damage.

You can send him a Kenzan or recharge or recharge and call Sangoku to make a kamehameha while you recharge.

Some characters in higher difficulty are harder to fight as Cell Freezer Vegeta.

For example Cell does all the time explosive wave, Freezer him when he is the Ray of Death, Vegeta is the attack with lots of kikoha

(It seems to me that this attack that of Vegeta cancels the final Flash if it is done at the same time)

what you can do, too, is when you hit if your opponent is protecting himself, stop slightly and hit again.

If he does not defend himself anymore, you can perform 4-5 strokes and chase with a Kenzian or a Meteor Combination.

For people that looking for alternatives.
Guide I Used: I used this to get S rank on very hard and expert as of the time of this comment.
ONCE YOU SEE 30 seconds appear and you don't have a blue health bar, restart. S is guaranteed with this method if you do it fast enough.
Though the assist times now take longer than in the video, it's still easier. Just watch for the annoying doge with a chase follow up to grab.
Try to perfect one round, then quickly get your ability gauge up and lower their health and finish with the awaken ability.
Sometimes when they dodge and come running towards me to attack, i try to quickly use a counter ability to keep the perfect going.
If you want another good combo, press the x button (xbox controller) or normal punch four times, then follow with hundred rending fist, then switch to start cheesing or start cheesing already.
