I've been playing a ton since I came back from vacation, probably have about 50 hours in 10 or so days. I'm loving the changes they made to D.VA, she actually feels useful to her team now. Also loving that Zen doesn't die to farts anymore, and that Bastion might be a little more useful in attack maps (and in general) because self-healing now builds up his ult. Plus, the new character is pretty hard to play, and fun.
Personally I'm still having a blast with it. I've put in over 300 hours between quick play and both competitive seasons, and I'm super excited for the new character, maps, and game modes. But I do want even better games throughout the rest of the generation, for sure. I think Splatoon for Switch could be amazing with some good features and if the Switch is popular.
Btw, welcome to TNE! I fixed a bug that was preventing you from choosing an icon and signature, you should be able to do those things now.
