Some people just don't like the other classes and let be honest here, it's really just too frustrating to go through the vault every week and get nothing but ass shards that you can't use because you don't have any raid gear cuz the raid just keeps giving you shards. But I've got a character of each class but I only ever play my Titan, and yes I have actually considered deleting a character to make another Titan because I'm sick and tired of not being rewarded for my hard work every week. Probably not gonna do it though because It won't matter in a month. Strange coins are different, you can only ever use them to buy things from Xür, and he only comes around on Fridays and Saturdays selling only 4 different exotics that you probably already have or have better ones and some speeder upgrades. There's absolutely nothing wrong with piling up your coins for Xür.
