WWE 13 difficulty and move thief

[dpforumid]

Although it is played in Legend Mode and my opponent(infinite), I feel easy.
Do you know how to play wwe 13 very difficultly?
options->gameplay->match options->balancing(a.i. reversals/damage/general)

Do you know how to control the three of balancing effectively?

Do you know how to steal your opponent's finisher?
I tried to press buttons as the instruction explains, but it didn't work.

MOVE THIEF(Steal your opponent's Finisher)
When your opponent is grounded, hold R and press up to enter the Move Thief State.
A stored finisher icon is required.

What is the problem?
