I know, but they still look cute. Wide, round heads, large round eyes, chubby little bodies, they're designed to bring up thoughts of children. You can make a small race and not make it cute, this is just one of those moments that draws from JRPGs that I dislike. Also, bawww everyone picks on them 'cause they're small, that's like the signature of mary-suedom.
Yeah you can like 'em if you want, but personally I feel they follow too closely in the design footsteps of previous "short, adorable" races and with the darker, grittier take on everything else in GW2, that feels out of place.
