Arguably these should be adjusted based on their rarity (which you can find by sorting the Achieved column).
For example Monster Kill should be one of the highest point values, instead of being less than GunGame Multi-level.
I don't think raising the value of getting a monster kill would be a good idea. There are players that will literally find a couple of hiding spots and camp at either spot for a monster kill when they have no chance of winning. Then again I just started playing again so maybe my opinion isn't worth much... lol
