Sadly doubt wow can do dyes
Buut as for me
No more armor type restriction bar class specific. So only say tier sets would not be transmoggable on all characters. But a lock could transmog plate for or a warrior cloth. Just illusion magic so not lorebreaking in that sense..Unless pur classes are meant to only enjoy a certain look/style lorewise. In which case wierd.
Let us use grey/white items.. sometimes i enjoy the idea of a simple look and in wow that is VERY hard.
Unlock seasonal items for year round use
Let at LEAST wars make a 2h look like a 1h for those who want a dw 1h fury war.
