You should be good at every mode on every map. I couldn't have said it any better myself. And yeah, you are telling players that. But it's not a bad thing. It would have to be with a selected pool of maps/gametypes that the community agrees are good. I'm not saying we NEED to use this method, I'm just saying its a great system for the type of game splatoon is.
The maps that "certainly people would want to strike off the list" would probably not even be ON the list since those would most likely be maps that aren't as competitively viable. And if they are and it's just team preference then i don't see why a team should be allowed a "get out of jail free card" so to speak, being able to skip their "bad gametype" every round. Instead they should be forced to actually improve on said map and work out their kinks. Here is an example of
a map rotation. I can assure you there are very few complaints of "they pick for us, wtf", but then again, halo is a long established franchise with an established meta. I'm just trying to make the community more aware of what are the most common systems in the genre. Not saying we need to follow that exactly but its definitely a good option.
Now, i have addressed 2 main points in my posts, none of which were criticizing players of wanting to borrow from other games. The first one, addressed the idea of choosing one gametype over the other. In my post I provided examples of games in the genre to emphasize the fact that there is no need for choosing one gametype just because. We should be choosing as many as are competitively viable. So I wasn't downplaying borrowing from games, just saying that 'ONLY ONE GAMETYPE FOR TOURNAMENTS JUST BECAUSE' is not the best attitude.
My other post in part addressed the fact that many people in the community seem to be relating splatoon to smash too heavily, probably because that is the main or only game (or game genre) they have experienced competitively. I think you'd be hard pressed to say anything other than that splatoon is a very very different game than smash (i mean honestly, there are very few similarities) so i think it would be better to learn from communities like halo, Cod, TF2, cs:go, GoW or any other relevant games. I'm not saying we can't learn anything from the smash community, but I am highlighting the fact that smash shouldn't be our main template, seeing as how it's in an entirely different genre.
You'll notice in my post i said "so people need to stop looking ONLY to smash bros for comparisons". I purposefully wrote "only" in caps to emphasize that comparing to smash is okay, but comparing ONLY to smash is not a great idea.
So I'd say that your accusation of alleged hypocrisy is pretty moot.
