Well, as you know, TAG4 maps became ranked in 2009-2010 and then they were prohibited to rank as they are too difficult for players (even for Cookiezi, val0108 and other asians which don't think that that maps were made only for 2 or 4 people). So, we can make them rankable again with some rules which won't let them OMGFREAKING impossible to do.
1. Comboes.
Beatmap must be divided by 2 or 4 combo colours (for TAG2 and TAG4 resp.). If distance by element is more than 2,50x, you need to make a new combo. Beatmaps with wrong combo system won't get ranked if they are even perfectly made.
2. Sliders.
As you know, this map has very rapid sliders which almost nobody can pass without missing. More problem is for CTB players: as they have droplets which can't turn to hyperdash, they are TOTALLY IMPOSSIBLE to pass. So, if TAG2-4 map is fcable by ctb player (I mean, passing sliders, some moments are too difficult (pixeljumps, for example) to pass without losing your combo), it is fcable for most of osu! players.
Sliders are passable when their coefficient (BPM x Slider Speed) is less than 400. For example, 190bpm map has 2,00 slider speed, its coefficient is 380 which is passable for all mods (some sliders with coefficient over 400 are passable for ctb players when they are not horizontal, so, if the angle between horizontal and slider is bigger but less/or 90, the slider has more chances to pass. This rule is in 90% for CTB players because osu! players can pass EVERY slider (it only depends with player's skills).
3. Distance.
Even if the map is for 2-4 people, don't forget that 99% of map players play solo and there mustn't be any jumps with distance more than 7,50-10,00x because it will be turned to hell even for 4 players. And, of course, there mustn't be "jump streams" like here or here.
If you think that this thread needs much more rules, write here and I'll add them if it passes to this :3
