Well I would say what your missing is the savings in server resources so populated zones can perform without lag, reduced strain on servers with less concurrent connections. enabling a lighter traffic load. as well as a way for people to be auto logged out when they get the rare bug of being disconnected but the session staying on the server. now instead of needing SE to figure out about it an hour+ later, they can rest assured 30 minutes would be the max time.
also if you followed yoshi-P you would know that they were working on this early on, but switched to increasing server capacity. the Dev's likely realized that this feature would save them immensely not just for players but for their own infrastructure. very similar reasons WoW, TERA, and many other MMO's have done.
reversely what are good reasons to remove this feature? I listed good reasons to have them we can debate.
