^ That's one of the reasons I'm not very interested in playing online. I never played Wii U online, even with friends. I played the 3DS version online with a couple friends here and there, but it was really only a good time if we all mutually agreed to goof around. The competitive Smash community is allegedly not as toxic as it used to be (not sure what the frame of comparison is, though), but they still take things way too seriously for me to want to involve myself in it. A lot of the smash modes seem designated for tournament style events, so I haven't thought to touch them yet. I don't mind the increase in intensity for the standard smash mode, but it's pretty situational especially in regards to rulesets. I hope one of the next few updates makes some tweaks to the rulesets or something so I can adjust additional things to appease my finicky habits.
When I play Smash, I usually always use the same style of button play regardless of the character, so I pick my mains based on characters that I like who also happen to work with my moveset habits. I'm not flexible enough to main characters who play too differently from one another, unless there are really unusual circumstances. Smash Ultimate is no different in this case, though with the massive roster, I find it to be even more true. I do the same stuff regardless of who I'm playing as.
