No, that's not what I meant. What I'm trying to say is, is that I feel there shouldn't be an option to only play as one class. This is because I want to be a Necromancer/Something, likely a Gearknight. Now then, were the option to play as only one class available to the player base, then I would feel like my Necromancer/Something was less of a necromancer than just a pure Necromancer. From what I'm interpreting from HJ's proposed class system, you're a combination of your main class and your subclass, thus creating an entirely new class combo altogether. However, it's your main class, the class in which you're fully versed in, that plays a larger role in defining your character's abilities, meanwhile your subclass is a class in which you're not completely proficient in and affects your character's abilities to a lesser degree than that of your main class.
And while I can see where you're coming from, Daax, I'd advise all serious role-players like myself to simply get their heads around the fact that while your class combo, for all intents and purposes, possess the utilities of two archetypes, a true role-player should and quite easily could see past such limitations. And besides, what if each class combo is a unique class all its own and, in pertaining to lore, is taught as a single profession? In other words, what if the Necromancer profession wasn't taught by itself, but rather is only a word used in the game mechanics to show that your class combo utilizes necromancy?
