As a raid leader and all of his/her helpers, it's about working out the strategy, figuring it out and implementing it, making whatever your raid's composition is work to beat a boss.
And as a raid as a whole, it's about spending however many tens, or hundreds of attempts to down a brutal boss and the rewarding feeling of a great huge group of people all beating a huge fight together.
In PvP, even at its largest organized scale - 10v10 ranked BGs - no single battle feels like the almost insurmountable hurdle that an extreme fight such as Heroic Lei Shen, or Heroic Rag, or Heroic Lich King can feel like. Going all the way back to Lich King for example, when you start that fight, it is just this MOUNTAIN of challenge. A long fight, with no truly easy phases. Lots of coordination - tranq shots gotta happen within split seconds, stuns on val'kyrs must be coordinated and happen right away and on demand, soaking spirits needs to be taken care of on a rotation, you need a competent leader in the spirit phase and the raid has to stick to that leader (let's not even mention the hell that is doing defile correctly) - and it all has to happen in one pull. Getting it all to happen at once is a big deal, and it's just a load of fun when you actually get it down.
So yeah, maybe it's like working at a bank with really fun co-workers... if every time you closed a transaction at the bank, you got a big cut of the profits and fireworks shot into the sky.
