Balanced Rework to Mr. Kim
Currently the way Mr. Kim works makes it so its not worth using in large parties due to not stacking with Bonus Exp. This is fine as Bonus Exp is a custom feature and it should have never worked with it in the first place. My suggestion is to still allow Mr. Kim to work in large parties but the Exp that gets boosted from Mr. Kim only applies to the normal exp gained from the monster, not the exp gained from the Party Bonus.
Looking at the EXP gained from Mr. Kim if only applied to base exp from monster, its not much better than replacing it with a tapper. (These are all averages based off memory. The numbers might be off but the general idea is the same)
Average exp in a Nif Party from Dullahans after Bonus exp is calculated is about 9-10k (Without Kim)
Average exp without Bonus Exp evenly split is about 1500-2000 after taps.
Calculating 180% bonus to the Normal exp is only an extra ~1200-1500 exp.
The Bonus Exp is then ADDED ontop after Mr. Kim is calculated
Keep in mind that Kim takes up 2 slots that are not tapping so you are also losing 2 taps for having kim up.
This change will make Mr. Kim still functional to iRO standards and will not increase the current Exp/Min rates by that much. It will also allow people that have Mr. Kim dancer/bards to still be worth recruiting in large parties.
TLDR- Make kim only work on Normal exp given from monsters not the Party Bonus EXP, This makes having a Kim Duo in your party basically just a slight better version of having 2 tappers in addition it makes Kim Duos not useless characters in large parties.
