I don't agree with the view that "upsets" are in any way desirable in preseason play-offs. They are an instrument through which you aim to craft the most enjoyable season – entertainment value is secondary. The unnecessary inclusion of additional (and quite frankly undesirable) candidates simply adds more variables and therefore more potential for randomness of outcome. Obviously you still expect the “favourites” to qualify, but so much can go wrong outside of their control when forced to play four matches in four days – not to mention the very real possibility that they are unable to field complete rosters due to short notice and inflexible/demanding scheduling. As a neutral spectator, bolstering the potential for these particular teams to be eliminated in playoffs (through an excessive number of matches) when they so clearly and significantly boost overall interest in the season itself is very concerning. At the end of the day ETF2L isn't just a league – the seasons constitute the entirety of the European scene for any given third of the year, and if they aren't able to reliably facilitate the teams that actually generate interest from viewers, then it is not fulfilling it's function.
I appreciate that some kind of play-off is necessary, but for it it to be on this scale seems like either cowardice or incompetence. It is very clear that some teams have a lot more to contribute to the season than others, and by making them jump through so many hoops the admins risk severely diminishing the enjoyment of the season for everyone.
