Don't feel stupid.... it's just part of the process that prompts more questions. It's a learning process and sure some of us can spit out the answer w/o thinking about it too much but, it comes with experience. 99% of the people here have probably experienced something similar over their years of building up their portfolio of credit.
Now that you've gone through it you'll know what to look for on the next one or even get them removed. If they're close to expiring off your reports you can do an "early exclusion" request ahead of time 3-6 months early to boost your profile even further.
WF is kind of funky when it comes to approvals anyway. Some seem to think they're relationship based but, they're not because there have been profiles I would have pushed an approval on but were denied for a checking balance. They're a bit conservative in comparison when giving out limits though as I managed $7500 from them when others handed me 20K+ at the same time.
It's an alright card if you have a specific plan for it and the $300 bonus was my reason not the other perks. They even denied the charges because it was a new card and thought it was fraud so had to call them before even being able to really use it. Since then though there hasn't been any problems with dealing with them or the card. It's nice though now that they have the points eraser like redemption method in place instead of the increments they used to have.
There are other options out there though with similar benefits if you want to go sniping with specific CR pulls. There's even a couple of places that on the pre-approval screen tell you what your CL / APR will be before you actually hit submit and get the HP.
