what happened to that doom bots game mode?

Urf is ok and all ( though its filled with only op champs so that's kinda lame) but since it was october, why didnt they just release Doom Bots of Doom game mode? personally i think that would have been more better and fit the actual month/holiday. . . . I hope for December they release poro king instead of just more urf.
. . . Maybe they should just keep urf as an annual thing once or twice a year, that way they can actually balance and change it a bit better to keep it fun and spicy. instead of nerfing op champs making them unplayable (garen), just buff the shitty/unplayed champs so they stand a chance.
