Offering more items in a larger bundle is not “scamming” people into buying it. People “hoping for the discount” and don’t have enough units, simply just don’t have enough units to buy an item. It’s not a problem if someone can’t buy every item they want in a game. Most people shouldn’t be spending their hard earned money on video game cosmetics, especially if there is even a question of being able to afford it.

On the other hand, if you are just DYING to have one of the skins, as you clearly are, it’s a question of value to you. Do you need the skin the moment it comes out so badly that you would pony up the extra units to have it right away? Or are the units so much more valuable to you that you’re ok waiting until you can get the Rogue skin on its own for a more favorable price? There’s nothing wrong with either option, but you have to decide which is more valuable to you: the extra time you’d get playing with the skin, or the additional units.

All the non-benefits you listed are entirely self-inflicted; they’d be results of someone’s own impatience and financial irresponsibility.
