Ashes of Creation lets players choose between action combat where you aim your abilities at opponents (and you can miss) vs. tab-targeting where the game locks all attacks on a target and does not miss.
Simply press Z to turn on action combat, as the video shows!
It is a monumental game design task to balance 64 classes with all their unique skills and action combat vs. tab-targeting to make the game challenging with no overpowered builds.
I personally love action combat and want to see it in every MMO. Tera is the most famous Action MMO built on action combat, but it did not rise to the fame of World of Warcraft, not even close. I am hopeful Ashes of Creation will surpass WoW 🙂
