i think kits are very useful and you should definitely keep them, but maybe change a few little things, like so:
first off there are some kits like musician that i personally, and i wouldn’t be suprised if people agree, is pretty useless and not really needed because you just end up with having many music discs that you can’t stack in a chest somewhere.
however that being said, there are some very useful kits like cookie lord and builder (i’m not too much of a builder myself but i know there are many that like it) and they shouldn’t be changed too much.
also i think there should be other items added to kits, not sure what categories or anything thought, but things that are easy but annoying to obtain like leather and books (i also always need leather if yall got spare x)
i do also agree with you that kits maybe a little overpowered but i have an idea for that, maybe if the lower levels have simpler kits where there’s stuff they’d need/want and also one or two surprises, and as for higher levels they could be more rewarding stuff as a sort of congratulations on getting to this high of a level which would also make people want to get to them higher levels (also maybe as a thank for staying so long and dedicating time to this server). i also think that kits shouldn’t just stop at a curtain level because as you reach the cut off point you may become discouraged and no longer have anything to work for (on that note i think there should levels higher than 30 because i’m sure there’s people who could get higher).
overall, love the idea of bringing back kits and there are more examples of the things i mentioned i just chose the ones that popped into my head of these aha but you get the idea.
note: you could also host a poll or survey to better help understanding of what people may want and you can hear everyone, it could include questions like:
how long have you been playing diversity?
what level are you?
have you ever look a break and if so why?
what is the main think you like doing on the server?
is there any items you feel would be useful in kits?(not too op)
what kits (when they were still available) did you feel was the most useful?
