Summary of class observations:
-Jett is a very simple class with no mechanics that reward certain playstyles or features that uniquely distinguish it for multiplayer. There is no actual synergy or overarching theme amongst the skills, and the v210 update simplified an already one-dimensional class while removing useful skills.
-In the context of Maplestory's other classes, its only noteworthy aspects are its good mobility (although less so with v210), good link skill, and strong Legion block.
-Due to lacking any benefit for party play (benefits that are unique to the class and cannot be supplied by any other class), it is assumed this class is designed to inflict damage in a multiplayer setting as opposed to a support role.
-There are also too many active buffs including Galactic Might, Bounty Chaser, Slipstream Suit, Bionic Resilience, Gravity Booster and Maple Warrior. With 5th job skills and decent skills, there can easily be over 9 buffs.
-Despite having high %HP from its skills, Jett is fragile due to lacking any invincibility frames or means to reduce %HP percentile damage, which is the only way bosses deal damage in relevant, high level gameplay.
-There is virtually no burst damage.
People can cap dmg on Reboot already, so dmg isnt the problem. BM has like an hour timer, and Bera cleared within 30min. It's difficult but not impossible, the only limitation really is waiting for certain capable people to reach 275 due to level penalty to have solid team composition.
You pretty much described the point of Reboot, and why it doesn't needs the extra lines. The last part specially is where the difficulty comes from, and if you are lacking then you get a party. Mobbing is not that important, or difficult anymore so its not a good point of comparison.
With all that being said why don't you go to the normal server instead? With trading and a bit of luck you can get to the same amount of progression you had in Reboot in a short time, for free.
Reboot being harder was intentional. Lacking in the damage department helps in making it harder.
How is that bad game design?
"Bad game design" is used too loosely anyway. Just because YOU don't find it fun, doesn't mean it isn't fun for other people.
The whole point of that decision is the make the game more simple to deal with and harder as well.
This is good game design for people who want this kind of thing. Just because it isn't your niche, doesn't mean it isn't someone's.
Lose/Lose, a game that literally deletes files off your computer makes for an awful game. But it was designed to be like that.
As Aggraphine said, why not just go all the way and add in the rest of the normal server stuff?
As a reboot player, I can tell you I don't want bonus potential.
The draw of Reboot is both that its F2P and that its meant to be harder to make it feel "like Maple of old" where you had to put effort rather than money. That's one of the reasons behind Reboot, take the difficulty away and it becomes a F2P normal server that generates less money. I would give you the bonus pots but that does defeat the purpose of difficulty in Reboot.
If you give reboot scrolling and bonus potential, you may as well give them player-to-player trading and an auction house to boot. And for the sake of game balance, the reboot-exclusive passive skill should be removed too. No need for literally free damage and higher meso drops when you have scrolls, bpot and trading.
At this point, reboot becomes functionally identical to every other server, there ceases to be a reason for it to exist.
