Waist is 100% sure the t4 lookalike from karazhan (or gruul / mag). Definitely t4 era.
Gloves look kinda like t5'ish. Kinda. Or some unpopular non-set crap :> Every other generic druid item looks like this. Could be pvp as well, season 12'ish?
I'm 99% sure you can't see the wrists. What you think is wrists-slot is part of the gloves - or chest.
Got a new staff, and I've changed back to one of my older sets. I tried out some other things first, and ended up wasting a lot of gold on transmogs I thought I liked but ultimately wasn't happy with. Anyway! Here it is:
I have loads of mogs for various chars, but can't post any of them as I don't have the right post count, funny since I just joined to take part in transmog threads argh, but I'll be back with them at some point I guess :P
Guess I'll just list the pieces >.<
feathers of Akil'zon
deadly gladiators dragonhide robes
deadly gladiators dragonhide gloves
belt of the twilight assasin
Black ice polearm
Without showing helm/cape
I have a whole bunch of tier sets which are nice, I especially love tier 7 after trying to get tier 3 back in the day, but I fancied a change and put this together, I quite like it.
Edit: photo below, this set is real easy to put together too, mostly bought with gold, then shoulders from ZA (but not the bought ones from shatt, different colour).
The shoulders are from the first boss in zul'aman, there is the same model in shattrath that you can buy, but it isn't the same colour to match the robe unfortunately, hopefully you get lucky and get the drop first time drop rate isn't too bad.
