Hmm...let see....
1st,lass can shoot shuriken when double jump which very usefull in gorge(PVP)
When you double jump,people try to knock you down,use shuriken,you can make them stop in the air and they fall(if lucky they fall straight to the hole)
Then the grab,he grab really fast,just it will get worser if the user is lagger.....delay grab you all the time....
The attack is very....lame......damage too low....
About the MP skill
1st:very usefull to knock people down and high damage
2nd:Only got 50% rate to fatal people....don't use it much in PVP
3rd:Use it when you cornered people,if not,you easily miss them
I think you should use more skill 1
When running from enemy,use run when the place is flat,use double jump is place like elven forest.
That what I know.......but I use Las 2nd job in SEAGC mostly(which is hyper pusher in gorge lol)

Fufufu......
