Are you limited to 10 at a time? I'm gonna be opening about 180-200 packs here in 2-3 weeks (need to finish drafting). I would think opening 200 packs like that would be kind of annoying, honestly.
Still caps at opening 10 at once. There's a universe where we could use something similar to this to enable opening higher counts of boosters at once, but, as you say, there would need to be some extra safeguards or tweaks to make that not be annoying. (I usually open 100-120 packs at once, so I get it.)
