Given the choice between "I have all my loot and don't wanna do coil anymore" and "I have to coil at a later time again because reasons", SE decided to go with the longevity complaint. It gets them more money in the end, and that's what's most important :/

You want a guaranteed piece of loot each week, but SE wants to keep you playing for longer than that. I don't think ANYONE would be opposed to getting more gear sooner, but it's just not in SE's financial intention.
