Haha, I'll try to.
I play quite a few gatcha games, so I'd like to think I'm conditioned to not get what I'm after, but it doesn't make it any less difficult (the disappointment).
Well, in addition to all of the "bugs" Gumi introduced in Chain Chronicle (increasing the health of event bosses so the people trying to fully LB the characters spent more in-game currency to refresh their AP/BP, decreasing the chance for those event bosses to drop in the first place, and outright lying about certain characters not dropping from event chests, despite the game explicitly stating that they do), the worst part is how they handled the closure of the game.
In short, they held continuous back-to-back events, with premium gatcha associated with each one. Players, not knowing any better, spent real-life money to purchase in-game currency to pull in these gatcha, many going so far as to fully LB some of them (that required to get the initial drop, as well as four more of them). This was shortly after Version 2 launched, so everyone was exited with all of the new content, numerous gatcha, and building up their teams.
Then, shortly afterwards, Gumi announced plans to close the servers for the game, which left players with a sense of disappointment, after all of the hard work (and money) they just sunk into their accounts. It's theorized that Gumi knew ahead of time that there were plans to shut down the game, but they already had the events translated/coded, so they released them anyway to get a few more dollars from their players. It worked, judging from the people on the forums, who put everything they had into these events, thinking that their support would be continued in the years to come.
Now, some say the reason for the closure wasn't on Gumi but SEGA. Personally, I think it was all Gumi, since they were already working on another one of their games (Phantom of the Kill, which completely failed, not surprising given how CC was handled), and they wanted to designate more of their resources on their new "cash cow". It just left a sour-taste in my mouth, which is why I was so apprehensive over playing Brave Exvius when it was revealed that Gumi (and not Square Enix themselves) were behind it. I'll remain F2P, just in the off-chance that the same thing doesn't happen here as it did in CC.
Granted, Final Fantasy is a much more popular franchise than Chain Chronicle, but it's not as though the latter was suffering from a low-player-base. The V2 release of the game brought many people back, both new and old, and everything was thriving. No one, myself especially, expected the sudden closure. I had a team I worked really hard on, and got lucky with several of my gatcha pulls. It's a shame I didn't get more time with them.
