k since i've been screwing around and playing for fun rather than tier whoring... using Clark (L), Iori, Mai...
i gotta say Mai is fun as hell... her Vega stance is totally awesome... and overall her XIII version should've had what she can do in XI in the air...
besides that... since we know Iori's LDM sucks balls... lets see good ways to combo into them since there are barely any... there are 3 characters that can help him land his LDM where the damage will be worth it...
Kula - hop C, s.C xx qcb.B, f.D xx QS, Iori LDM
Gato - hop D, s.D, cr.B xx qcf~qcf.A xx QS, Iori LDM
Silber - hop D, s.C, f.A xx qcf~hcb.A *2 hits* xx QS, Iori LDM
