Yes, but a lot of the cool stuff back in the day is now standard play like sapping off CC, deathing/saccing CC, grounding deeps, purging NS.. even 2200 hunters knock people into traps they miss and 2200 spriests use lifegrip to avoid them. Back in WotLK it was sort of rare for a lower rated HPal to sac a CC. Now, it's common practice at very low latings.
I used to do cool stuff back in MoP as a Ret like blinding a priest when he went for a guise fear, freedoming an imp CS pet nova -> sheep, insta fearing psyfiends,1 shotting them to get a clutch crit heal, pre-kicking MDs etc. These days, there isn't really jack shit i'd be impressed by seeing in a video because almost everything that used to be innovative is either standard play or has been removed.
A lot of that is due to pruning, sure. A lot of it is also that people have been playing the game for much longer now and the general skill-base of the game is higher, while at the same time there's less to do to separate players from each-other.
