"Deserving" is a strong term in that matter, but what is a "protagonist" anyways?
I have been trough many situations where the "frontman" was not doing anything, just a mere puppet to present to the public. The real deals have been done in the background.
And in that matter I think the Lalafell could be easily placed in that role. They are the underdogs, and usually only seen as small people, often connected with children and such. That they are clever, grown-up (no pun intended!) creatures is often overseen. This can go the other way round, too, when you have the big, muscly man that is basically an empty shell and useless for any task (apart from lifting weights). In almost other game, the small species (or race as you call them) is the one that has "hidden" strength that put them into an unexpectedly important role: The Asura with their technology such as waypoints that also revive, travel, general intelligence and such. In LoL, the Yordles build machines or are swift and cunning. The Mascu in bless are merchants and inventors. Try to mess with them, that's like messing with Amazon, Google and Apple at the same time. The Tarutaru were excellent mages blowing up armies with their magical abilities. The Lalafell are just widely written to be shallow and with no depth, but still waters run deep, eh?
