It seems like the MC might now have two fighters at his disposal, which helps a lot. Now that Tamaki has defeated a couple of orcs handily, she shouldn't be as scared anymore as before. I doubt she's ready to fight an elite orc yet, but the lesser ones shouldn't be a problem.
Their team now is balanced. We have:
Fighter with healing aka monk like but with weapons instead fists
Fighter with wind magic
Debuffer with earth magic which means can also tank some stuff with earth wall or prison or something else
Buffer with summoning magic and act as tank
We still miss a pure tank and healer though. The party will increase in +1 or 2 members I believe.
Now the joke of them leaking may end to become a meme between them. I can already imagine the newest member first fight will leak and the girls will say something like: "welcome to the first fight leaking club" just to ease their minds of they weren't the only ones doing but ended to surpass the fear and become stronger.
