I don't know about you guys, but the way I perceived English was not about the grammar (obviously), nor the way of writing an essay. And although these 2 skills are necessary, there's another important skill this subject teaches you that is far greater than the aforementioned ones: it is the way you can find meaning behind things.
Take this forum for example, there has been a ridiculous amount of sarcasm and humourous assertions, only to express their views on English. So therefore my answer is yes it should be compulsory and yes it should count towards your atar due to how important it is. By finding meanings/motivations behind things, I would accurately presume that: business deals would go smoother and patients of the medical profession will be easily dealt with (and another example, section 2 of the umat)! So, in turn, by finding meanings behind things, we are essentially saving lives due to how crucial it is.
