When to use
It is only viable as a wall combo, otherwise Kazama Style 5 Hit Combo is not that good to use in actual gameplay, as most of the time the whole string can be blocked. The first two hits are occasionally used in juggles for wall carry. The low is completely safe on block, so that can occasionally be used as a bait for using his b+2+4 parry to open an opportunity to punish.
In Street Fighter X Tekken, this move became slower to execute when he damages the opponent in five hits.
