It is. That is pretty much what you will be spending all of your time on. But I typically use learn to refer to things you can train in training mode. Combos, defense, oki set-ups, ect. I probably worded my original statement wrong. To me, knowing how to zone and what to do in neutral comes from match experience and I can't get much from trying to do it in training mode. Of course, I could just not know how to do it right.
And I just consider her straight forward compared to other characters. When I compare Lambda to characters like Rachel, Mu, Carl, Relius and some others, her playstyle seems very simple and straight forward. Not saying that it is really easy to effectively zone with Lambda though.
