That may be the case for some, but probably not all teams participating.Why couldn't you play 2 tournaments at the same time? That's only 2 games per week, I guess you can spend 2-3 hours per week on these tournament games if you are taking a part in them.
Also I think not everyone who wants to play with no restrictions is gonna play BEAST, and that's alright.
Anyway, there's a poll that will decide if BEAST gonna be played with restrictions or not, and all these conversations are useless, anyway you won't go against votes. Just in case I want to mention that some teams won't participate in beast with no limits.
An alternative would be an intermezzo event that is not planned to last 2 months, has fixed fixtures and deadlines and teams can play matches up until then. Sort of like the winter break.
The "pain" it would be to play without restrctions would be less time-consuming, whereas data is pretty much equivalent. While that would make teams play more than 1 match per week on average, it'd be more flexible and less of a long term commitment.
It could rely on BEAST#4 rosters, but people would play for badges instead of promotions and the whole thing might be done in a month. Best case, we get a patch that makes the game more pleasurable for everyone and BEAST#4 can get going as the community intends to.
Call the intermezzo run BEAST#3.5 with a twist. Purely hypothetical of course.
