Discrepancy between some monsters

Hello!
While i was searching for some good niche places to my friends level up (more specifically one priest partying with a white knight, so fireweak+holyweak mobs) i found something pretty interesting, for some reason, some mobs are EXTREMLY broken compared with another ones, in a point where it is completely USELESS going to another map
It is normal some maps being better than other ones, better drops, spawnrate, map design, but what is this???



CD:

• Have a insanely good map design, flat with 3 plataforms, perfect to party play
• Five times higher exp:hp.
• When you kill one, they multiply theyself into another mob with a 4.8x higher exp:hp than Klock.
• The spawnrate plus this mechanic of multiplying when dead make every mapler hit 6 mobs almost 100% of the time.

Klock:

• Cool teeths and somehow nostalgic.
• Cool TP, good only for card hunting (very good addition tbh).
• Map design extremly good to make less epm than a islander.
• They have Dark Klocks.
• They're not always angry like CD's, hits ways less.
• Elemental weakness (hey! thats why i found that abysmal difference).

(almost same exp, almost 3 times weaker, insanely good map design too, and CD's makes they look bad )

While i know every monster on this level range can't stand against CD's supremacy, i don't understand any reason for staff keeping things unbalanced at this level, the only problem is changing the original exp table, maybe you guys don't want to do it, but i think it is more fair than nerfing these maps, since 99% of the playerbase already abused it.
Mobs on a higher level like master death teddies, grim phantom watches are more balanced than this, so thats why i think it isn't intentional.
