Dodge is an ability just like SC. Dodging isn’t a class, that exotics are dependent on it doesn’t change the fact that it’s an ability.
It doesn’t nerf the exotics, it nerfs the synergy based on the ability. For the exotic to be nerfed they need to change the exotic.
Likewise it can’t be a class nerf because SC doesn’t make up all of Titan melee abilities.
I redefining things is popular but conflating things that are very different is counterproductive.
