Auto Spiritshots: This is currently the best way we can have them work. You can use them manually in pvp to gain the extra casting boost, and use auto-bss for farming. We will try to fix this but it requires a lot of work.
Spiritshot/Soulshot consumption: All Soulshots/Spiritshots used are always +1, this is a security fix. I know it makes you waste twice the Soulshots and Spiritshots in A/S Grades, which is why we increased the wight limit of every player therefore they can carry more. Changing the client to make everything +1 will take forever and it is not worth it as we might find a better fix for that.
