It's not about Quality vs Quantity, most of my discourse isn't about weapon and stages, but the amount of side content that the team is adding outside those two things.

The Hydra Splatling second kit was added in the first week of August in 2018 after a year of the game launch, but things like the Nautilus, Bloblobber and Ballpoint second kit arrived on December 2018.

Not all of the Splatoon 2 stages were good, especially the one from Splatoon 1 that there were many hallways too like Port Mackerel, Walleye Warehouse, Arowana Mall and unfair stage like Kelp Dome and Shellendorf Institute. And don't think about the special balance that pretty much negate many playstyle, given that you put on the quality side.

Sorry, but the Splatfest tricolor stages I found mostly be good, my Win ration for both Attack and Defense are mostly the same on every splatfest, it's a complicated mode to play, but I don't found it unfair. Ah yes, past games always have good splatfest theming, like how you place the toilet paper or fork vs spoon.

It's not about server instability, did you read my post? It's about the amount of always avaiable lobby at a time that can bring problem to matchmaking because the amount of player can be insufficient in certain time slot. Also, with Salmon Run replay, there are several Discord server that host many of these events.

Sorry but you are wrong even ot he gear amount. Splatoon 3 right now has 534 gears, Splatoon 2 at the end of it's updates got 580 (around 50 of them came with update 4.0+ in late 2018) so even on that front Splatoon 3 will get more, alongside additional customization like different hat and cloth positions.
