Ruckus will only "attack" (or defend) your network if you check the "Defend my network against malicious rogues" box on the WIPS page. Otherwise, malicious rogues will just generate angry log messages and possibly email/text you if you have alarm notifications turned on.
If you are in the USA though, be aware of the new FCC enforcement advisory regarding wifi blocking. If you're a commercial establishment, it no longer appears legal to block another wifi network. Although this originally stemmed out of a Marriott price-gouging paid wifi case, the wording is so broad that it seems like even this kind of WIPS where if you marked a neighbor's AP as rogue or somehow your AP's mis-recognized their AP's as rogue, you might be in a bit of hot water. This article is pretty good:

I'm not sure what would happen in such a case -- I would expect your own ZD would warn you that your network is experiencing a malicious rogue sending deauth packets on your behalf, which would give you cause to investigate.
