Missing an eye also makes depth perception harder, from what I've heard. Distancing is one of the most important factors of a fight, so that could be a big disadvantage if you want to go that route. I honestly agree with what everyone else said, find more personal flaws specific to who they are rather than what they are. That being said though, Lalafell probably have a few obvious flaws, mainly physical.
Honestly, I've always thought of Lalafell (either folk) as being one of the more intelligent and quick-witted races. All of the things I've listed here probably can, and are, overcome by them fairly easily if they put their mind to it. I'd go with what everyone else suggested mate.
- The world is built for people bigger than them. He might have trouble reaching things in daily life.
- Little legs that they have, I imagine they have to put in a lot more energy to move as fast as, for example, an Elezen who can just stride along.
- If they fight, they need to be a lot smarter than a Xaela or Roegadyn who can only rely on their strength or weight, respectively, and still do well. He'd also need to take in to account that a hit from one of the larger races will probably do more damage to him than one of his will do to them.
- Continuing on the vein of the last bullet point, I imagine being a Lalafell Brass Blade, soldier, etc. must be a lot harder than being a Highlander and doing those jobs. I imagine they'd need to train a lot harder, not being as naturally physically gifted.
