I love the cutoff feature, I think it's pretty great. But it's also quite frustrating as it generates a lot of extra traffic. I understand that there's the delay profiles but that doesn't work for something that you want quickly, but you'll eventually want a the blu ray version of, as you end up re-downloading it loads of times.
I often find that as a series is running I'll want it straight away, but sometimes I might wait a while before I watch it (or may even just want the blu ray version later). I'd still like it to get it straight away just in case I want to watch it. So, I set a load of qualities to be sure that it grabs something. Still, I'll want the cutoff to be BluRay because that's the ultimate target.
Say your profile is the following:
BR 1080p <---- cutoff
This can in some cases result in the same episode being downloaded up to 6 times (though that's pretty rare, more often than not it'll be 2-3). This is pretty annoying as generally once you've got it and it's just aired, you're happy to accept a lower quality one.
Instead of it going all the way through the list, sometimes upgrading in small increments, it would be great if there was a checkbox to say "only upgrade if at cutoff level". That way, it would only download it a maximum of 2 times - once for the quick "it's just released, I want it now" time and once for the actual target quality you really want.
