The stun on TNT actually didn’t make it through WotLK, even, let alone WoD.
Yes, Lock and Load no longer triggered on freezing traps as of WoD which was a shame, but they did make it have bad luck protection with Black Arrow; you were guaranteed to get at least 1 proc per Black Arrow and the chance of procs scaled with Multistrike. This was pretty good since in WoD Black Arrow’s CD reset when it was dispelled. Not as good as guaranteed procs from freezing trap IMO (which also played into the theme of the spec really well) but evidently it didn’t hurt SV Hunters too much since they were gods in rated PvP even as they got canned in PvE after 6.2.
God I miss the spec so much.
But the primary thing I like about Hunters post-WotLK is Focus. I think it made the class much more dynamic and involved and thematically it fit much better. I know some people don’t like it but personally it’s my favourite change they ever made to the class. It was actually meant to be in Vanilla too but they didn’t get it done in time so they went with mana instead.
