Relaunching

I've kinda just accepted that disconnects are gonna happen constantly (blizzard when i GET you), so I'm wondering if anyone knows how to make the game relaunch faster.

I've seen streamers who's games close for genuinely 10-20 seconds before they're right back into the shop, meanwhile every time I relaunch it takes a minimum of 60 seconds, assuming I instantly ended task as soon as I noticed the freeze (which is not often because sometimes it likes to fake you out and reconnect you 5 seconds later), which of course skips your entire shop phase from like turns 1-5. Also I do always close everything in the background as soon as I try to relaunch, but it doesn't speed up the relaunch time.

I've heard people talk about using firewall to disconnect faster, but afaik that's more for skipping combats so I'm not really sure if it's what I'm looking for. Save my mmr reddit please
