This is something I could never understand. The Bajorans are one of my favorite alien races ever because I felt like they had more dimension to them than say a Vulcan and Klingon. The Bajorans were like modern day humans which means you could get alot of drama out of them and I love that they use to be slaves basically. They gave them a tragic feeling which I felt worked. I mean you could tell Halcaust type of stories or stuff about religion or do stuff on terrorism. There was so much material to use with them. Who cares if they don't look really alien and just have a bump on the nose. I never felt hav unique looking aliens was important in trek because aliens are very mainstream in that universe. While bumpy aliens are not ideal for all shows it works just fine for Trek IMO.
