I'm pretty much a transmog-a-holic. I definitely have splurged quite a bit on transmog items for all my toons this expansion. Off the top of my head, some of the big ticket items I've purchased this expansion alone include:
For my Rogue:
- Full Bonescythe (200k+)
- Full Dreamwalker (200k+)
- Battered Hilt (6k)
- Blade of Wizardry (10k)
For my Paladin:
- A couple pieces of Dreadnaught (80k)
- Glorious Chest (5k)
Plus another 20k or so all the other stuff I've bought for my 7 90s.
