It's not the best idea in the world necessarily. Just would be nice to have the option specifically to practice the fights we're wobbly on in EC.
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.
