More people who don't know of the "hairstyle rotation", so here it goes again:

Each major patch:
1) ONE race gets ONE unique hairstyle that others cannot have yet, like in...
2.1 Roegadyn
2.2 Elezen
2.3 Highlanders
2.4 Miqo'te

2) ALL others races (with the exception of the race that obviously already has it) get access to the "special hairstyles" from previous patch, meaning:
In 2.2, we got access to 2.1's Roegadyn hair (with the exception of Miqo'te for graphic reasons);
In 2.3, we got access to 2.2's Elezen hair;
In 2.4, we got access to 2.3's Highlander hair (dreadlocks, and that headband long cut for males).

So calm down, you'll get them "damn catgirls"'s hair in 2.5.
