Why do we need abilities to give a WR a route

I understand these are part of the game but some of these are silly and make no sense for example my 12 year old and his friends who are not on a team run decent routes, so why would a professional or a legend at that status need different abilities for them to know how to run a route shouldn’t they know these things already , there pros and legends  how did they become this if they didn’t know?  shouldn’t my RB player easily know how to run a flat route why does running back apprentice suddenly give him this brain knowledge?   i think abilities that make sense should be in the game, shedding and extra jumping  etc.  things like that not ones that make no sense.

You have to have/use an ability to make a professional athlete...jump. Period. It doesn't get any dumber than that.

So they can add updated abilities throughout the year that, coincidently, make existing cards obsolete and require replacement.

Because EA is the worst company on the planet. You can rush 3 and stop the run and get instant pressure. The game is a disaster and it will only get worse when more abilities and AP limits come out. Abilities have really ruined this game
