How much has the raid comp changed since retail?

[Maviand]

Hello!
I used to be in a progressive build back when TBC was retail. As GL, we used this raid comp (trying to min-max) as much as possible.:

I am wondering how much has changed in time. We use to switch Shamans in DPS grps (from tank and heal grps) for lust on DPS.
PS I was the tank-stacking agility bear druid who would swap to DPS in fights.
