>>Is there any chance that 1213 and 1216 could be updated to behave like just about every other group spell and immediately affect the group upon joining?

I tried to add those on the initial release of group spell mechanics, but those (and bard spells) were really odd and require rethinking/redesigning the spells to make them compatible. It's something I intend to circle back to at some point, but I've a large list of higher priority items at the moment.
