Although Monster Life finally got updated in the Tune Up update, the changes were far too small. They should have added the following changes as well.

1. Rename Oddities to Robots and Oddities
The majority of new Oddities added in Monster Life are Robots that I once suggested to have them added in the past. Calling all these robots Oddities really triggers me. The monster type should be renamed to ROBOTS and Oddities.

2. Increased Farm Level Cap, Active Monster Slot Cap, Monster Barn Slot Cap, and Waru Cap
Monster Life needs increases on some caps. The new Max Farm Level should be 50, the new Max Active Monster Slots should be 35, the new Max Monster Barn Slots should be 15, and the new Waru Cap should be 100 million.
EXP required to level up to: 41 = 100k, 42 and 43 = 125k, 44 and 45 = 150k, 46 and 47 = 175k, 48 and 49 = 200k, 50 = 250k

3. Improved Lucky Box
Regardless of your Farm Level, Lucky Boxes give a trifling amount of Warus. What needs to be done is every time your Farm Level reaches a level that ends with a 5 or a 0, the contents of the Lucky Box will be upgraded.
Chances for each item:
1-4: 2000 = 70%, 5000 = 20%, 10000 = 10%
5-9: 2000 = 50%, 5000 = 30%, 10000 = 20%
10-14: 2000 = 30%, 5000 = 40%, 10000 = 25%, 25000 = 5%
15-19: 2000 = 10%, 5000 = 50%, 10000 = 30%, 25000 = 10%
20-24: 5000 = 30%, 10000 = 45%, 25000 = 15%, 50000 = 5%, 1 Gem = 5%
25-29: 5000 = 10%, 10000 = 50%, 25000 = 20%, 50000 = 10%, 1 Gem = 10%
30-34: 10000 = 30%, 25000 = 40%, 50000 = 15%, 75000 = 5%, 1 Gem = 9%, 2 Gems = 1%
35-39: 10000 = 10%, 25000 = 45%, 50000 = 20%, 75000 = 10%, 1 Gem = 12%, 2 Gems = 3%
40-44: 25000 = 30%, 50000 = 35%, 75000 = 15%, 100000 = 5%, 1 Gem = 9%, 2 Gems = 5%, 3 Gems = 1%
45-49: 25000 = 10%, 50000 = 40%, 75000 = 20%, 100000 = 10%, 1 Gem = 7%, 2 Gems = 10%, 3 Gems = 3%
50: 50000 = 30%, 75000 = 25%, 100000 = 20%, 250000 = 5%, 2 Gems = 14%, 3 Gems = 5%, 5 Gems = 1%

4. Updated Life Extension
It's strange that the only regular monster rank that requires Gems to extend is S rank. It would make more sense and be more convenient if we could extend regular S rank monsters with Warus instead of Gems. The cost for extending regular S monsters should be 270000 Warus. But extending all 22 types of monsters all at S rank will cost about 6 million Warus and trying to recover 6 million in just 2 weeks is overwhelming. So what should be done as well is make extending monsters' life add 1 month instead of 2 weeks. As a bonus, it would be nice if we could extend SS rank monsters as well. Regular SS monsters should cost 4 gems while Special SS monsters should cost 6 gems.

5. Gain Farm EXP for Releasing Monsters
There are currently 2 ways to gain farm EXP, completing quests and nurturing your monsters. But there needs to be a new and faster method.
When you release a monster, you gain farm EXP based on the monster's rank and level.
EXP gained = (Rank of monster) x (Level of monster); C = 10, B = 20, B+ = 30, A = 40, A+ = 50, S = 60, SS = 70; Example: Releasing a level 30 S rank monster would give you 1800 EXP.

6. New Monster Types
With so many monsters in the game that aren't in Monster Life, there should be 3 new monster types added.
Aquatic - Effect: Combo Kill Orb EXP +20-140%
Pests and Critters - Effect: Combo Kill Orb Interval -1-7
Humans and Manlike - Effect: Rune Buff Duration +2-14%
