I play alts for a few reasons. One is that I have different characters and I like to rp a bit with them. One is that I found a name I love and ended up creating an alt just for that. Another is my main is a male miqo'te, and while outfits are too damn cute on females, fantasiaing every other day is unreasonable as well as I still enjoy playing him as him. So for the last I can be both male and female for the same character at the same time so to speak.
