Since you already are using a powered speakers you basically have a "driverack" in each of your QSC speakers. These are already processed with the proper limiting,eq and designed to use there crossover point. The "auto RTA" functions produce ok results at best and could put you further from your target. A good eq used to make cuts to compensate for abnormal things in the room sounds like the ticket for the OP.
A PA system definitely takes some tuning to get it right. We sometimes have a opening band and you can learn alot about your system and get it tweeked a lil before show time. A sound guy inst something we work without. However a bad one can be night mare also.
The drive rack does way more than than EQing and is way more involved than the panel on a K-12. Pink and white noise processing ,volume adjustments . They can be used in power speaker situations too.

I have to agree, one could have problems with the wizard, but many venues are successfully using this system and wouldn't do without it now that they know how to use it. not bad for $500. you can pick and choose what you want it to do, in the case of crossovers, turn them off. this may be way more involved for the OP, but a rack of EQ's for each instrument aint cheap either. This will eq the final sound to the room, according to its purpose, in stereo too.
