Sword Users are left out!

Hello people I'm new on toram but I noticed that as the bosses gets harder the more sword users are left out.Yes it's true that we need to tank in order for magic users to cast their spells but is that all we do? Sometimes we can't even tank because we don't do that much damage.Its kinda getting unfair for me
And I know to other sword users too.It feels like we're getting useless in parties /boss raids and etc.I just hope devs will do something bout this.

Thanks for reading
