The problem is the luck factor of the whole thing. It's all well and good saying that you should "grind for the items", but how can you grind for an item that is in low supply because no one can actually obtain the item? Sure, you could do your daily objectives for a week to get a case, but with a 1 in 100 chance of actually getting the item you want, it's not worth the effort.

If there were alternative ways of obtaining rare items such as suits, then maybe you could grind for them and get them, but as it currently stands, it's either not worth it or not possible. Your argument is invalid.
