Wow! That's a nice decrease. Congrats. I too inherited Chase Bank as my cardholder for my Slate card after the demise of WAMU. I have not seen my rate decrease or increase since I opened the account in 2008, just before Chase took over. It's been four years and all of my payments have been made on-time. Time to see about a rate decrease for me.

Surprise me. My JP Morgan Chase Flexible Rewards Visa Card had a Chase based rate decrease from 12.24% to 9.90% apr on purchases with cash at 19.24% apr. First time Chase has done anything for me since the bank card came over from WAMU (2008). Note the card had 8.99% apr purchases and a cash of 23.90% apr with WAMU. Makes me feel warm and fuzzy.
