that because in the novel this conversation is in 3 times.
First, teamates trash talk about MC. That not logic, now he is gone why they still like that. Then they said even if MC was competent they still wanted kick him out. Newbie understand MC wasn't fired because of he's incompetence.
Second, between two donjon. They realised their level went down and newbie save them again and again but they don't think of MC absence. They think everything will go fine after a while. Phoenix have his flashback about his past and why he glue MC.
Third, after the donjon, Newbie initialise the talk and propose the hypotesis where MC was competent XD
That funny because even if they level go down, they refused to imagine MC doing something for the team.
The archery was know to always strike vitals points, now she hardly touch her target. The warrior use a heavy weapon and flashy move no one can imitate but now the enemie no long in his sword way.
They said a black mage only do 5%, 10% at most in debuff but MC was doing 50% debuf from the begining.
I prefer the novel in this point because they find fault at everyone.
Phoenix because he never grow up hide behind MC like a child.
Teamates because they blame MC and choose they jalousy instead of the team.
MC because he hide his power and compensate the lack of skill of teamate without tell them where are there blunder to let them grow up.
