Also, my CL's haven't moved for quite a while even though I started w/ a $1000 QS1 and upgraded to QS and now at $8K. Savor is stuck at $3K so i've moved to just using my Apple card instead of those 2 cards.
Same. I stated out after my BK7 with Cap 1 and put tons of spend on them each month, sometimes 2x the CL. I got minimal CLI. Did the same with NFCU after my secured card "unsecured" and now 2 years later I have large CLs with them (14.5 and 25K). At the same time I asked NFCU for a new card (which resulted in the 25K CL) I asked Cap 1 for a CLI on my 2 QS cards. "Sure, here's a $100 CLI for each card". So now they're sock-drawered. I'm not going to close them, but just put my paper subscription on one and something around $20 on the other and let things go. It's not worth the headache thinking they're every going to give me CLs like NFCU, or Apple, or Synchrony.
They used to merge but I think that stopped a while ago (maybe).
I merged two QS's together and then merged a Venture into the combined QS that became one great big $51,500 Quicksilver. Didn't last long as CapOne reduced thwe credit line to $30K after about a year.
I can't get that card to do anything now.
Sorry for your frustrations, @Creditwiser, but yes it is well-known that Capital One doesn't do CL consolidations, may or may not adjust APR, and limits the ability to product change their cards. The whole package makes them fairly inflexible to deal with for enthusiasts like us.
I sometimes question hanging onto my Quicksilver but I keep hoping they might sweeten the rewards or offer product changes that will benefit me. (I am only offered original Venture/Venture One which don't interest me.)
Still, they keep surprising me. They've given me additional CLIs in the past 12 months with little spending. Your posting reminded me to ask again tonight and they boosted me by $2K from $28K to $30K, so thanks for your part in that! 
Hey @SpaceCityCCuser ,
FYI, that image is from my C1 upgrade options.

I saw this post and it made me start putting heavy spend on my Visa QS. I want to PC it to a VX but my current limit is not 10k. We'll see what happens.

Have you checked your C1 PC options lately? I was hoping your QS MC would be openned up to the Savor offerings.
I've checked it often, @NoMoreE46, including after I saw your post. Still just original Venture and Venture One. 
Not sure I would PC to Savor/Venture X and miss out on the SUBs anyway, but those cards interest me more. In past two years, sometimes they have offered just Venture One and sometimes both. I wonder if I put heavy dining spend on QS if that might trigger a Savor offer but I already have great dining rewards on other cards. When I put spend on WS, it's most often general uncategorized spend. Hoping for Venture X is probably unrealistic in my case since my QS is a MC and VX is a Visa product.
