Mass Effect has a problem like this as well. I've almost played through the ME series twice now.........Why can't I say a couple of words just because I don't have a certain amount of Paragon points?.
You should really get it by the second run.
Paragon options are for people who take the paragon path and choose to create that kind of personality.
A kind of 'Paragon' if you will.
The same can be said of your renegade options.
A sort of 'Renegade' character.
You have to choose which path you take, if you choose a path too neutral you will have created a neutral personality meaning you wont have enough points because of your decisions.
We'll call those choices.
The 'Choices' you make will determine the in game personality for your Shepard, if you choose not to go the path of a 'Paragon' you will not get those options. You will instead be given the options from the 'Renegade' path. Unless you've played the game from a point of neutrality.
This is a problem because playing out as a neutral Shepard has absolutely no special benefit to the player at all.
So maybe the solution is to give the neutral player a benefit. Some kind of diplomatic mind control power or green prompt, that allows them to negotiate reasonable terms. Or a post on the Citadel or Pacific Islands at the end of the game, as a reward for successfully prosecuting your neutralist, centrist philosophy or pacifist movement.
You could move up in rank with each installment as you gradually work your way up the ladder to eventually become councillor Udina's Junior Assistant or coffee dispenser. Working for free to avoid an industrial dispute over drone labour.
This will allow players to experience the thrills and spills of not really caring either way. Or the glory of not actually caring at all. While still being able to tell themselves things like:
Hey, you earned that coffee cup.
Or
Where's my burrito?
Knowing they sorta did the right thing around the time they were ready to do it in. But where does that leave us in terms of the current state of the current installment? They've likely already decided on a system and will likely stick with it, like we likely would if we were likely to do such things.
We'll call this 'Alike'
So people are essentially in limbo, they will likely never have a neutral option or a Galaxy's Greatest Middleman mug and will likely never find out what happened to their long lost Burrito.
Ah, humans we're not so alike after all.
These not so brave but not cowardly either people are on a quest to find someone 'alike' and in the absence of such a place, to find such people, they deserve to be able to create such a world; represented in a character who finally represents them.
Wether bioware likes it or not.
Which is why I highly recommend you play this game on a pc. Modders will have a solution to your problem and if you doubt what they can do you need only look toward the thought provoking, heart warming and ultimately superior ending they created after EA murdered Casey Hudson and had him replaced with a replica robot.
TL;DR
Google MEHEM bro you'll see what I'm talking about.
