Set default pricing tier to Free
Customer complaint the default pricing tier is not Free(if the service has free tier).
Based on his 20 years experience as a software designer, Yahoo! commercial platform senior engineer, and e-commercial website designer, he realizes things related to money is sensitive and need to handle carefully.
This time he just changed his deployment region to other one, the system changed to (add a new) App service plan which pricing tier is S1. He said customers are easily mislead and choose wrong pricing tier.
So please set default pricing tier to Free if the resource has free tier.
