The Raiding in WoD is top notch imo despite lack of other content or the repetitive garrison/shipyard missions and mini-games. WotLK' Raiding and WoD is probably best WoW has ever seen/been at. I really enjoyed every single fight in Highmaul, especially Imperator; god what a blast that fight was. So far I am 5/13 Heroic in HFC and it's been great, the other bosses look as challenging and engaging as ever, can't wait too progress more. Blackrock Foundry was also great and reminded me a bit of Ulduar in terms of how it was structured and freedeom on where you can go and tackle whatever you want.
I have 0 complaints to WoD's raiding content, probably best since WotLK imo. Wasn't a huge fan of MoP's setting/mogu/klaxxi raids, but SoO was great (expect for the Shaman fight due to annoying trash cleaning). Cataclysm raids were okay, but Dragon Soul was absolutely abysmal and anti-climatic compared to WotLk, MoP and WoD endings.
Those are my 2 cents.
