You are right, of course - she was fast and strong and our MC is just a newbie but... they gave him powers (mainly claws) that should have been used more effectively/prominently during the fight, and also this doesn't change the fact that the whole fight sequence was pretty weak and not exciting as it could have been with a little more imagination from the writer/devs.She was stronger and faster than them.
They WERE weak.
MC may have powers and got them faster than other vamps but he isn't a fighter. So far all he's managed to do is take out one underprepared guy that was missing an eye.
They went against a feral that's been killing for years. He isn't on her level when it comes to speed and strength. It would be like putting you in the octagon against Stipe Miocic, you would be so far outclassed it wouldn't be funny.
One day the MC may be a badass, right now he's a child that's been given some shiny toys but doesn't know how to play with them.
My expectations about that fight were a bit different so I (cheeky bastard how dare he!) dared to voice my discontent and got facepalmed for it
Lesson learned, heh.
