Lieselotte is negative edging, and Dorothy is about traps and gimmicks (Literally). Zenia as aforementioned is about just framing her pile bunker, like Makoto's drive but much more strict. Combos in general are prettly lax, not as lax as BB but pretty easy. Don't expect any super hard assed combos for the most part.
Add me on PSN by the way, we should play some time.
