Yes, indeed. ZenBear knows exactly what I'm talking about. Anyone who's never witness that act can consider themselves blessed.

I've been running Sastasha, Tam-Tara, and Copperbell on my Conjurer from level 15 all the way to level 26 (and still yet to see one single Acolyte Skirt drop), and since level 24, for two whole levels of level synced dungeons, I have seen only one Gladiator doing it properly. All the rest of them use Riot Blade combo all the time. I could be riding on the tank's enmity after just Lightning and Aero, with absolutely no overhealing.

The class quests are supposed to teach about enmity, yet it doesn't tell new tanks that enmity is more important than damage for most of their time. I'm thinking this is the source of this problem, and people who do this are actually those who pay attention to skill tooltips and chose the skills after some analysis. Sad that they end up making the wrong choice because they don't have that key piece of information.

If the tooltips told us that "Combo Effect: generates 200% enmity" instead of just "higher enmity", then they would have been able to make informed decisions.
