I want regional. I feel everytime the topic of regional comes up, it's from the perspective of only NA and Japan and how regional would effect EU gets left out.
EU is much further away from Japan than NA and we don't have a direct route either. This is the reality of EU-Japan

That's from the UK, other EU countries can be higher.
No connection in the world is going to make much difference, nothing short of moving EU and Japan closer together will. Quite how anyone can look at that and say, it's fine, we don't need regional.
That results in constant nonsense like
Tanking enough hits to kill before the special activates, because they already had it on their screen.
Played every EU splatfest, and it's night and day difference playing with local players, compared to 250+ping.
EU playerbase at least has enough to support it. Since the splafest dates got changed, EU has had 2 days without either Japanese or NA players and it's been fine. There hasn't been excessive waiting, sometimes a little longer, but nothing excessive. That's S/S+ solo, can't speak for squad ranked.
Of course someone will say "but Nintendo are idiots, you get Austrailian players with high ping as well". True, but timezone differences mean you see very few at peak EU time and the odd player from AUS is still far better than 7 Japanses all pinging at 250+ to you.
Really though, the main issue is ping. 250ms is absurd for this type of game, there is no excuse for it, no one would willingly play with it. Games with server browsers, no one sits there and picks one with 250+, yet on this, EU players are forced to because "regional is bad".
Even if after EU getting ranked to ourselves and proving there are enough players, you still want to play the "split the playerbase card". The MM could and should at least prioritise ping and search outwards like so
<50ms
<100ms
<150ms
Keep everyone in the same pool, but playing with as low latency as possible. Rather than the current, it's 20:00GMT, 05:00JST, but still being match with 7 Japansese players and having to put up with at least 250ms ping.
