Is Generous Realtors' RERA history a red flag?

Spent the whole Sunday checking out options on Dwarka Expressway, including Reputed Test A. Generous Realtors ka project hai, and I started digging into their RERA history. Yaar, kuch old complaints mili. Not sure if just seeing 'RERA registered' on the portal is enough, especially with so many new projects coming up. I'm currently in a 2BHK in Sector 82, looking to upgrade to a 3BHK, maybe a villa around ₹3 Cr. Don't want my investment stuck later. Is it normal for builders to have a few RERA complaints, or is it a major red flag for capital appreciation? How do you guys verify a builder's actual legal track record beyond what's publicly visible? What specific things should I look for in the RERA portal or other legal docs before signing anything? My main concern is future exit options and getting my money back if things go south.
