Nyerk

Hi,
Im having an unstable ping (34-65 playing on EU) and i dont see that ill get to the point where i do 7k dps (last boss Library of Knowledge) with sin (55er kamp gear) other sins are able to pull off through weaving.
So my first question is: Do i just suck at it or isnt it possible with an unstable ping like that?
Secound question would be: Can i somehow compensate the lack of weav through enhanced attackspeed in as without blatantly increasing animation speed?
