The refugees have flooded into our server! #buildawall
On a serious note though, Nexon's lack of foresight and competence is really shameful, especially considering they blocked off Windia to transfer into because reasons. At this point, a server merge (NOT an alliance) is necessary to save the dying worlds.
Oh poor you, you have to hack in a game because you have to devote time to real life!
Imagine reversing that logic.
"I couldn't finish my work/job today, I was running out of time to complete Vanishing Journey dailies!"
Let's see how long you stay employed with that mindset.
Which classes? Aside from Phantom most of the classes only get a few quests, which only level them up a couple times, not all the way to 2nd job. I wouldn't exactly call that covered.
Explorers (if you count the Victoria Island questlines up to 30)
Cygnus Knights' new questline can get them to 30
Resistance if you do all the quests in Edelstein (including Demon and Xenon)
All the 6 heroes have their own questlines up to and past 30
Kaiser and AB
Mihile up to 30, where you try to find clues about Chromile, and help Cygnus
Kinesis in FriendStory
Hayato and Kanna in Momijigaoka
Even Beast Tamer in Arboren
Of course the questlines are optional in most cases, so it's up to you whether or not you'd want to do them or just train straight to 30. But a theme dungeon at that level wouldn't really be necessary.
