When they introduced the warden set, I got excited, but then realised that to fully immerse the set, I would use it as DH, for the warglaives, or use the assassin rouge , for stealth and fan of knife (the iconic abiltiy for warden from WC3).
But since the assassination spec uses daggers, the character woul be locked into that weapon type for transmog, and for warden the dagger looks weird, at least for me.
It would be nice if the subtley and assassination spec would get the option to transmog daggers to fist weapon for more option to make a character outlook.
