I think some skills are useful.
for example Recover HP or - DEF enemy
So some people need it
But while some pets Obtained good 1-3 combat skill, but no 4th combat skill
And some pets Got a 4th combat skill, but a 1-3 battle skill doesn't work
So if players can focus on combining pets to have a good 1-3 combat skill
Then use the Skill Book: Battle Skill 4 on it
It will look good
Players still have the challenge of fusion pets
- Player must fusion pets to get good 1-3 combat skill
- Players will need to fusion pets to get a 4th combat skill
I hope my opinion will be considered
P.S. we can get skill 1-3 from Altar, but not for skill: Sunder Armor, it only has Soul King
