The model is to churn out the same garbage each year because it saves them a fortune, knowing a lot of people will still pay for the same c*** each year. The whole thing is so ironic it's almost laughable.
EA need to overhaul the whole thing, the gameplay mechanics, servers etc. are outdated and inadequate. The bugs and glitches are consistent in each iteration but to overhaul something costs a lot of money and time so why do it when people keep buying their outdated, uninspired, broken product? You don't you keep churning out the same each year.
