I don't think the queen change will be as big as people are expecting creep wise. As was posted on TL, here is a picture of before patch and after patch.
The biggest limiting factor in creep will still be the APM of the player. It may make a small difference if they are 100% on top of tumors all the time, but realistitically outside of the very top levels it won't happen.
I'd say early queen ramp blocks in ZvZ will be one of the most significant changes to it, otherwise not that big of a deal.... or at least not as much as everyone is making out.
