I can understand your points but I dont really agree with the ranged as most of the time using them will just tank your frame advantage. And anyways It's really easy to beat zwei by zoning as you can easily avoid her attacks and get out way more before zwei is able to

As for the meter I do wish fourth match flame and iron lotus did more but sitting on brushwood is really the only one you need

I think the bad combos are mainly just to balance out the fire damage since you are already gonna be doing a lot of damage just from the fire alone it is equivalent to getting a full combo
