High Volume Duplicate Title and Content Errors: Scale of 1-10 How bad is this?

[Tippman]

I have 15k pages and 1.5K have duplicate title and content errors. the reason is I have a ring parent page with child pages for each of the size variations. On a scale of 1-10 how big an issue is this and does it need fixing?

IMO 10 and every bit counts, especially in a very competitive market where I am not ranking...

We have around 12,000 pages, our CMS dynamically generates titles for our deeper level pages which resulted in 8,000 duplicate title errors for our FAQ pages... After eliminating 4000 we have seen no statistically relevant differences in traffic. Its obviously not beneficial to have any duplicate title pages, but we haven't experienced any penalties..yet. The closer your pages are to your root domain the bigger the issue.
