I figure it could help in GCC, Trial 4, etc. Obviously there is no other very hard content, but hey.
Still GCC level 3 can be OTKO with crit teams, afaik, so... That's the problem and it's what people are whining about - there's SO much more content in the Japanese version, and Alim are really good at rewarding players and such, while Gumi are being greedy, releasing japanese vortex units in the gacha (Lin/Ren for example were vortex in Japan) and releasing new unique units in the gacha (this new dude is global exclusive, like Ulthor) and it's just weird.
Right now in Japan they've announced 7 Star starters, and to celebrate *EVERYTHING* is 1/2 stamina, all evolution dungeons are up, etc. People regularly pull Sphere Frogs from honor summons, they've had burst frog dungeons and raid for a while... Gumi is weird in that there's a very, VERY good system in Japan but they handle it very differently in Global, so who knows.
I have a friend who absolutely *loved* the game, but he's tired of it now because there's zero content anymore. He just quit playing, and he was spending money quite often, but now he's just super tired of it since he has literally nothing to do but grind to increase his level. These are players you want to keep, because they're a constant influx of money, but Gumi is taking SO long to bring content to Global and they keep doing cash grabs that just piss off the serious players that it's going down slowly.
