Thank you, credits where credits are due. To summarize my main issues:
Adventurers:
-Product/luck/hurt bonuses are cool but imo can be buffed too. Issue would be that bot accounts gain too much here.
-Hotel room is completely outdated. Either remove it or change it to include forts as well.
-FF bonus should be improved, either by keeping the same concept (it is nice, change it to a locked +-3k dmg and then % chance) or changing it to one of the suggestions given here/in other posts earlier.
-I see that people would also like a duel bonus for advents, which is fair because PvP is the main drive of any world (I think numbers support this as well). I'm by no means a good duellist so I'm sure other people can give fun suggestions here.
GENERAL: Give PvP bonuses for sure, other bonuses are pretty outdated. (sets give way, way more)
Duellists:
-Speed can be buffed imo, why not. Won't change that much.
-Change XP formulas before touching duel motivation. Duel levels still suck and bully duellers into less targets instead of rewarding them.
-Don't touch crit chance/damage at this point. Taking things away won't make people happy.
-Duel radius is good and a big bonus, might not even need any other change? Idk.
-Everyone should be able to see other people's current bonuses as a script does this already, it is irrelevant in the current state of the game.
GENERAL: Strong class imo, doesn't need that much changing since its bonuses have scaled (too) well over the years.
Workers:
-Extra XP is nice, can be buffed imo.
-Banking fees are outdated but nice bonus.
-Construction/motivation bonus is nice.
-Aiming/dodging bonus in FF's is quite balanced. It's not stronger than soldiers in tanking, and not stronger than duellists in damaging, so it won't be a real meta FF class, but it does its job. If anything it could use a small buff to bring it up to par with other classes but not that necessary.
-Same as advent I see that people would appreciate a duel bonus. Same as with advent, I'm not sure what could be added that'd be diverse enough.
GENERAL: Non PvP bonuses could use a buff, FF bonus is +- balanced, duel bonus would be appreciated.
Soldiers:
-HP bonus is probably the best in the game for FF and duels. It's hard to nerf that after 15 years imo, even though it would be somewhat justified with recent level updates. Maybe an additional 4HP/point (8 with prem) instead of 5. If not, just keep it, but it opens up justified avenues for other classes to be buffed more.
-Level bonus has become irrelevant, either remove or change it to diminish upgrade costs or something. Outdated.
-Tactic bonus for duels is also really strong, same as with the HP bonus I'd understand reluctance to nerf it, if a nerf is wanted 35/40% would be a start. If not, again, opens up options for serious buffs for other classes. Easier/more appreciated to give stuff than to take stuff away.
-LS bonus in FF is imo pretty outdated. I know people like the funny numbers, but it really doesn't do that much in reality. Giving 10/15 aim/dodge bonus to neighbours is nice, but ultimately doesn't do much. If anything you could take this away, or buff this to compensate HP nerfs.
GENERAL: Strongest class in the game imo, closely followed by duellist. Can do a bit of everything, I'd be reluctant to take stuff away. Just give other classes more bonuses.
TLDR: Buff advent PVP, Buff worker PVP, Duellist is fine-ish, Soldier would be ok to receive a (small) nerf if buffs to other classes are not adequate.
Game systems:
-FF still needs help, decrease overall LS scaling (this would lower complaints about duellers as general dmg would be lower). Also opens up the possibility to give tanks a HP nerf. Getting hit for 1500+ (being generous here) standard is not fun.
-Consider giving HP/AP pots when getting KOd in an FF. They're a major drive for activity in worlds and people should be rewarded by participating in them. I get it, UP is nice, but the average player doesn't get more than 15UP which just isn't enough for the average noob. XP still a joke btw.
-Change how duel level cap works and change how XP works as well. Doesn't make sense to keep that system when worlds are getting smaller and smaller and people need to intentionally lower their DL level by spamming hundreds of bible duels.
-Since nerfing church isn't gonna happen, buff XP for jobs by a lot. (Doubling XP isn't out of the question)
boost experiences from duels by a lot and make fort battling worth its time - hella experiences and bonds, maybe some boxes too.
