It is really stupid to NOT allow any team choose its own process. Your scrum leader is not a wise person, to put it lightly.
The other Scrum leader we had was pretty great, but, unfortunately, was not the one assigned to my team.
Sorry if this borders on ranting. I really enjoyed working for that company, but it was a rough time toward the end of duration there. Apparently I have lingering frustrations, especially since I'm still friendly with many on the ops team. :)
