Wow gold players didn't take talents that didn't give direct benefits.
A Classy Expansion, But Not a Talented One: Ever wonder why Druids could only be Tauren or Night Elves? Or why only Blood Elves and Draenei could be Horde Paladins or Alliance Shamans, respectively? Cataclysm will add a bunch of new Class/Race combinations to the game - Troll Druids, Tauren Paladins, Dwarf Shamans, Human and Undead Hunters, and Gnome Priests (to name a few).Variety is the spice of life, after all. (Or, "Holy Cow!").On the other hand, there won't be any new levels of Talent trees - there will be five more talent points with the five more levels, and remade and refined talents, but the 51-pointers will still be as deep as the trees go. On the other hand, Blizzard will be adding the "Mastery System" - while they intended for talents to be cool, fun options, they found that wow gold players didn't take talents that didn't give direct benefits: "More healing, more criticals, more damage."So instead, they will be taking some of those out of the talents, and putting them in the talent trees themselves - as the designers phrased it, it sounded like a Mage who put points in Fire - for example - would earn a boost to damage with every point he spent, no matter which talent it was in.Excavating the Path of the Titans - With only five levels, the problem that the designers faced was, how could players customize their characters in lieu of new talent points?BlizzCon 2009 will feature a variety of activities catering to the tastes of Warcraft, Starcraft, and Diablo fans.
