At a high level it makes sense for the brand and I'm all for rewarding loyalty to a brand but the way it was implemented rewards new customers at the expense of kicking older customers in the nuts. Once Lange created tiers in their product catalog and ADs, by default they created tiers in their customers as well but not necessarily based on past loyalty to the brand. Either the management team was too stupid to realize that many long time Lange customers would get left in the cold or they didn't care, I think the latter is more likely.
