"Why CTB maps can not be ranked?": Because it's not rhythm game.
I suggest to make new generation of TaikoCTB maps. Taiko mapper makes taiko map, CTB mapper makes CTB with mapped notes in taiko difficulty. Of course it's possible to make CTB map via standard qualities, but i find that incorrect. Some awesome patterns in ctb might be ridiculous and stupid in standard mode, but not in taiko. Taiko maps are not relative with placement of notes, so i think it's good solution
