I think the current selection of emoticons lacks variety, and it's missing some expression compared to commonly used unicode emojis. Basically, we lack sad crying ones , and laughing ones . The droplet one can be interpreted as crying depends on whether you think it is a teardrop, but it sometimes lacks the expression of defeat and disheartening. We do have happy ones (, and maybe ), but these lack the actual laughter and I sometime having trouble choosing one to ridicule or "lmao"...
