I hadn't noticed that as I don't play TT, but it might have just been as a tip of the hat to the youtuber they invited onto the Panel From Hell stream. His youtube name is "WolfheartFPS", so they may have thought Wildheart Barbarian sounded better than Totem Warrior Barbarian.
If I'm honest, I think Wildheart Barbarian sounds both cooler, and more descriptive, so I have no problem with it at all.
That's an interesting thought that didn't occur to me.
I just thought it was an issue with not wanting to use the word totem, as if doing so would be considered cultural appropriation.
