I dont get the argument that you can do any concept with just core rules.

[Vyvyan Basterd]

We are forgetting the biggest part of the core rules...rule 0

The core rules can get you close, but with a little dm intervention you can make anything happen.

I want to play a trained fighter, but I want him to have a little more skill points to finish off the concepts.

DM: Alright, how about we drop your hd from a d10 to d8, and bump your skill points by 2.

Its things like this that allow dnd rules to accomplish anything you want, its why we play pen and paper instead of video games.

Or how about -

DM: If you want a fighter with more skill points, don't use your INT as a dump stat. INT 14 = 2 more skill points per level and a fighter that can follow the Combat Expertise feat chain (if that fits your concept). Or (as others have said) multiclass.

Add a Tower shield to a Thrower and they have total cover until they choose not to.

Of course a tower shield counters any ranged.
