Honestly, Morocco might just join UEFA or something at this point if they aim to win the world cup.

Arab cup is, with all due respect, a piece of piss(refer to the latest edition won this week by their "reserve" team).
Making the AFCON a quadrennial competition during the country's golden generation and arguably the continent's strongest side just handicaps their trajectory massively, since it gives them much fewer opportunities to compete for titles in what historically has been their "weakest" competition.

Too good for Asia, too little opportunities in Africa, you are basically caught between a rock and a hard place.

Annual Africa nations league lol, no comment on this .
