Its not really anything grandiose as having some savior complex. I suppose the way I describe things it feels that way but its mostly an observation Ive been seeing with a lot of MMO communities where they demand change but are very much complacent whether it be out of obligation or because they're actually not as bothered. I guess I pretty much fall into this category, but I also know personally despite my criticisms I still find FFXIV to be an enjoyable time waster. However from what Ive seen from people and from how they act and post and discuss the game, to me it feels like some genuinely just dont like this game like at all. The negatives outweigh the positives for them and this is where you should ask yourself if the sub is even worth keeping. At the very least Ive seen people actually follow up on leaving the game because of their strong dissatisfaction most recently.
I mostly regard that "just unsub" advice to people whom are very much unhappy to what this game is now. Its something you can easily tell if you pay attention to the daily threads and posts they make where there's rarely if not ever an ounce of positive or constructive feedback. Its easy to call them a troll and that could certainly well be the case but if you cant trust somebody who's just overly positive and blind about the game....then why would you trust somebody who's overly negative and stubborn about the game as well?
I still firmly believe of just providing feedback. Somebody gotta still like the game enough to stay and voice their concerns at the end of the day otherwise how would the devs know what to fix? We cant forget that its thanks to those dedicated people on copium during the 1.0 days that 2.0 even happened, but it was also thanks to the mass of people who voted with their money to stop playing FFXIV that help drive SE to improve the game as well.
tl;dr we need both kinds of people in order to help improve the game. So if anybody ever fits in either criteria that Ive listed then do what you gotta do. You pay to play the game if its good to you, you stop playing and paying if the game is just outright bad.
