One more question This game have lot of skills like "cabal" "lineage2" or just basics like silkroad?

0:58 how can fly like that? Just use your flying skill? ^^
2:10 starts pvp. Probably an assa with a bow.. or a ranger with daggers :D
3:33 what kinde of class is this? Chanter i guess
4:00 Archers and mages can jump backwards to gain a little bit speed to dodge but thats it..

And it has alot of nice skills... lineage style i'd say.
