Good points regarding fairness of the format, but another issue with this format (or its schedule) is that after groups, there's 1 week dead gaps in between stages with literally no Worlds material at all, other than some tweets and content creators predictions. So the hype kinda dries out a bit. 2-3 day breaks feel right, but 6-7 is maybe a bit too much for the average viewer. Perhaps a more condensed tournament and with more Bo5s would be preferable?
There are never 6-7 day breaks, at least not until world finals.
For reference, groups ended on a Monday and QF began on Friday. QF ended on Monday and SF start on Saturday. So the break is 3 (G -> QF), then 4 (QF -> SF), then 5 days (SF -> F).
I feel the downtime for sure. I'm sitting here in my hotel room and the only direct work I've done since casting C9 vs Gen.G (outside of prep) is a 1 hour story meeting and then I'm back to having tomorrow off as well.
That said, weekends are pretty prime. This is an event that the entire world watches and that means someone's got the games at 5am and someone's got the games at noon and someone's got the games at 8pm, or thereabouts. You miss out on a lot of people if you don't let people have a weird schedule for a day or two to catch the games.
