The best way to map mania is whatever you want. As far as I'm concerned osu!mania's identity should not be some narrow minded overly specific style like most other games have (o2jam focuses on LNs, BMS mostly has few or no LNs, etc.). Osu!Mania should accept every style, so that players from every game can find maps they enjoy. We shouldn't try to come up with a single characteristic style that every ranked map should conform to. Let the mappers map what they want.
If you're going to ask about Entozer stuff, this is pretty relevant: https://osu.ppy.sh/s/235994 8.46 stars according to the page. Entozer says he can't even pass it himself thanks to the HP drain. Or how about https://osu.ppy.sh/s/178027 8.80 stars on the EX diff. Or https://osu.ppy.sh/s/156500 at 10.80. If these all had proper difficulty spreads, are these considered acceptable? I can't pass any of these, but I think they're all good maps in terms of the patterns.
