This is a perfectly reasonable reason to want more open lock outs IMO. BUT the pain it will cause long run will not outweigh the benefits .My suggestions are
1. DO the run on alts to tighten up.
2. Deliberately wipe if you're not learning and try again.
3 Learn from your one attempt a week.
If I enjoyed my Alts half as much as my Main then I would agree with you but as this is not true I disagree strongly.
I like my Main and Alt are only for emergencies not just because the game has no good ideas for playing mains.
