We will continuously develop or make changes on various contents specifically for the TOS English Version so we hope everyone knows about this in advance. "
From what I am reading on forums it is worse than the KTOS version with instant dungeons getting reduced and everything that was annoying with KTOS making its way into ITOS. So how is ITOS going to do any better than the failed KTOS???

How has the game failed in Korea. It’s worse from what you found on the forums? Maybe you read too much into the angry rants that are going on here. There are several justified concerns that are actively being discussed - which is great! - but it’s nowhere as bad as a prelaunch forum would make it look.
