Since you can link j. d.D into normals now, I'll just include that in my midscreen combos. Try these out, though I don't have the damage values for them yet.
2 bar, 1 drive
j. d.D, st.D, qcf+D, d~u+K (1) [DC] qcb+A, qcfx2+AC
j. d.D, st.D, hcb f+AC, qcf+C, [SC] qcfx2+P
j. d.D, st.D, dp+K, [DC] qcf+AC, qcfx2 + P
1 drive, 3 bar
j. d.D, st.D, qcf+AC, ~dash~ qcf+K, ~delay~ d~u+K (1 hit), [DC] qcb+P, qcfx2 AC
Tried these out and they work just fine.
