I can hit pretty much all of Lambda's combos on both netplay and offline now (the ones I care to do, not that 2366D stuff). The only reason I drop combos is due to my own horrible execution at doing TK crescents when I have absolutely have to do them.
Tao combos on the other hand...I can sort of do them offline but when I get online and drop a single one, my brain goes on standby mode and I forgot how to do any combo with her and just mash random shit.
