As an individual, I don’t care, as our group is fluent, as European, we try to engage communities of the continent to spread FaB love, but Heavy Hitter will not have translated Blitz decks, which is sad for accessibility.
Boosters will all be translated, so skipping the blitz decks looks so weird to me.
I was thinking to buy 4 of them to 2V2 because of how thematic the arena deathmatch is.
Another point is that Blitz deck tends to decrease the market price of some cards (I still think playable cards should not be expensive).
This means some cards will be more expensive depending on the langage.
It does not seems to be a real decision but more a planning+production problem.
Reaching the European market is considered difficult and I suspect LSS is still a young company.
