[3.5e] A player insists on making a fighter... (opinions)

[Emperor Tippy]

If I were a player starting a new game and my GM's response was LOLWUT?! to me choosing a fighter... I would probably find a different game.

And as a DM my response would be "That's great, good luck and have fun in your new game. I don't allow my PC's to play NPC's."

I'm sorry but a Warblade makes a functional fighter, the fighter class doesn't (unless the player really knows what they are doing).
