iws+3,2 ender into f+3+4 is usually not so easy. From the convo I had w/ Tenshi a while ago, she said that ss a bit immediately after you are recovered from ws+3,2 helps f+3+4 (immediately after ss) to land.
for NSS d/f+2 juggle... this is one of the easiest high damage juggle I know.
NSS d/f+2 f+3+4 1 b+1 b+2,1~KIN f+2
Having no B! in this juggle is also a bonus. At wall, bound your opp w/ d/f+3,2.
