I'm not sure if this is in the right place so apologies beforehand if it isn't.
I need some advice on a member of our regular gaming group though. Myself and another member are relatively new to Pathfinder and roleplay in general. We stick to the core rule book for the majority of our characters/spells/feats etc. We really play just to meet up and have some fun. We have one other member though aside from the DM who is proving to be a bit of a frustration for us.
So far each of the characters he has made have been strange ones with combinations of skills from various books. Now these would be fine except they are not ones that you would naturally think up. Each of these characters we're pretty sure have been taken from pre-made builds online. Today's example was a fighter using a Sawback Bastard Sword and doing 2D8+8 damage (With his power attack on top. He's playing as a human. The DM looked into this and said it's only possible with a specific gameplay rule and even then would not naturally be thought to do)He's using theses builds to appear smart towards us all, claiming they are his own and we've tried explaining to him that this is just frustrating for the whole group as the characters are not wholly effective and when they are you can tell a mile away that they are not his, they're overpowered in some way and it's ruining the enjoyment for the 2 of us who are reasonably new to it all.
I may be just getting wound up for nothing over it all, after all they are his characters but it's getting to a point where the group is on breaking point simply because he is trying to play in this style. I've spoken many times with the DM about this but it's a fine line between letting someone do what they enjoy and limiting everything they do just to please others. How can we get it through to him that this just isn't what we want to game with?
