Hmm... You definitely have a point their.... But the Jump event could be test phase for players who had been away for a long period of time, seeing how they offer it in a fashion where players who are currently playing could send invites for existing players who aren't playing for a very long period of time, are getting a jump character. This jump could also become an in-game Kafra Shop item for existing users whom has a 1 main High Level characters and don't want to do all that questing from lvl 1, and I think it's currently in test phases for the team behind RO2. Right now it's a failure, seeing how the admins have to inject manually and how players have to send tickets in warpportal site for admins to inject jump event manually...
People probably dont realize the importance of a main character in this game. Say for example, I have a main with a full fledge BlackSmith. I could easily equip good gears for my low level characters, provided I have the right ingredients gathered by main character.
It is easier to farm with high lvl char on low level mobs for my other low level character equipment. It is slow when I gather ingredients on a low level char just to equip good gears. This saving time!
Now that I think about it... There might be more noel classes coming seeing how they are implementing this kind of jump event... Would love to see a gunslinger noels... I'll save that 'free' jump if I were you?!
Uh.. I also doubt this is testing for some future thing, but, other things here..
With how the game is now, artisan/blacksmith is incredibly useless for pre-ML gear. It takes too long to get mats for a tiny boost that is quickly outleveled (token gear from dungeons is better if you have someone to help you through, but, even random field drops/gear you get from quests outpowers crafted gear). Blacksmith is worse off since a Pandora's weapon will take you to level 40+. Maybe for some classes it can be helpful to have an alchemist for pots (SP for magic), but otherwise? I've leveled various characters recently, and the only help I used from my alts was starting off with 3 medium bags. I've even skipped dungeons and been fine with gear..
And no, I also highly doubt new Noel classes are going in soon. Given how slow development is.. we were given a loose "plan" for what will come out through June (which is when the jump event ends - saving is useless since the option will go away next month) and there was nothing about classes.
