CO-OP Vs A.I. Jungler

I don't understand why they have a duo top meta in all Co-op Vs A.I. games. It leaves any newbie or "first time with a champ" jungler no option but to leave the newbie top laner to their fate. I understand warding for an A.I jungler would be problematic for the very early beginner, but introducing a hard mode with a jg meta would be an easy fix. By the time your average summoner learns smite they have laning fundamentals already, but no understanding of a jg champion until they get destroyed by one over and over. Riot has a lot on their plate, and that's understandable, but adding an extra learning tool can only improve the community and skill level of new players. And I know If I feel more comfortable with a champion, I play that champ more often, and if I like that champ, I buy $kin$ for that champ XD. Please comment below if you feel the meta isn't accurately portrayed by the duo-top Co-op Vs A.I. games, or if you have any other suggestions, glhf on the rift guys and gals. -Pantallicus
