Mercenary best killer in the PvP, How about ladder? for me, ladder with mercen is so easy, you must know the combo of side kick/wall combos or rising slash combos or bombs away combos.
I think, rising slash combos is a perfect combos than wall combos. you need a faster skill and timing.
the combos is:
dash --> soccer kickcombos --> hit, hit and hit --> impact punch --> hit, hit, and hit --> destructive swing --> rising slash --> soccerkick combos --> heavy slash --> impact punch --> hit, hit, and hit --> demolition fist --> stomp --> tumble --> soccerkick combo .....
when the enemy run, you must make him fall, use circle swing or whirlwind.
Bombs Away Combos:
Bombs away --> flying swing (the enemy fall in front of you) --> roll attack --> whirlwind --> stomp --> tumble --> soccerkick kombo --> hit, hit, and hit --> taunting howl --> demolition fist.
PvP full strenght
