I play a Miqo'te because I LIKE the race. I didn't want to play a boring Human, but Lalafells are too... puntable, and I toyed with an Elezen a bit because I like Elf type races as well, but they are too... disproportionate in my opinion. The only other race I seriously considered was a Roegadyn (in fact, I have a Roe alt). But Mio'te was the one that appealed to me most, and even after playing around with the other races I didn't find one I liked better. It has nothing to do with visual effects, weird cat girl fetishes, or whatever, I simply liked it the best. My go-to races in tabletop and LARP (given the option) are cat-people or Elves, so seeing as the Elezen look weird to me, I went Miqo'te. Everyone has their preference, and it's not our fault you chose wrong
Honestly, I don't know why people keep whining about it anyway. It's not like having an over-population of Miqo'te effects your gameplay in anyway.
