I'll not to write a thesis here, but I've talked about the rulesets as far back as 2014. But it boils down to rounds mattering more, forcing aggression, and the aforementioned time management aspect.
It's not like we don't already use this ruleset in scrims, events / cups, and community LANs. And it's also not like teams don't already park the bus or play slow in scrims let alone matches let alone playoff matches No playtesting is required, unlike other things we've thought about in the past like tether speed removal, shortened round timer, etc. .
You could play playoffs earlier under the NA ruleset, but that just means you either have less scrim time or scrim earlier, neither of which are very appealing options. Does it really make a difference if you finish at 3AM or 4AM? As for the whole playoffs on weekends thing, I imagine that top Invite players don't want to spend an entire week scrimming and then play on the weekend after that. Not without LAN. We haven't had an Invite LAN in over six years by the way.
Yes, halftime is good but their role can be entirely replaced by tac pauses, something I think doesn't get utilized nearly enough (nowadays or ever). Give each team a five minute tac pause that they can use to assess the situation / make gameplan changes. I guess halftimes on KOTH maps would be fine, though I don't really understand why we play to four to begin with. Having first to two halftime for KOTH is fine, but I think I'd rather play to three without them. And pauses can still be used on KOTH, too.
It's time to move on from the old ruleset. We had it because of ESEA. We had lots of things because of ESEA. But now we have more freedom, and we should take advantage of it.
30 minute maps with 3-5 minute round timer is fucking sexy.
