should i change from blade to axe ?

_howler_ - Lost City

OK on pw my-en i lved my BM to lv 62 b4 changing servers and he used axes

upon comming to pwi i decided to go blades for better accuracy and to pvp with ( 5 str 3 dex , 2 vit )
but now i am lv 65 and am dieing alot( from mobs mostly) and its making it harder to lv, so i was wondering 2 things

1. should i restat to a pvp axe build ?( i got like 900k sp atm XD)( i still wanna be able to kill archers)

2. if so how much should my dex and vit be ? ( i know axes need 3 str per lv)
