That's one of the things I'm very much hoping Bungie changes with D2. The depth of character customization/progression. *** Granted: we don't know really anything about character progression in D2 yet *** But, whether you hate Destiny or love it; the character progression was pretty shallow. Even with the different circles/nodes that you could fill out in any of the sub-classes, there were still only a very few combinations that were viable to play. Thus, for each Main Class, there were only a very few, select "character builds" that a Player could utilize that would still leave their character viable for the content in the game. In D2, that character customization/progression needs to be much, much deeper IMO. Give us double/triple the amount of available Nodes to utilize per character sub-class. Make more of them viable in a wider variety of combinations, which will lend itself to creating more and more interesting characters that can fill more roles in a Group, and fill them better. The sheer lack of character class diversity in Destiny is one of the major things that turned me off to the game, but I would love to see Bungie take this issue seriously and not repeat this mistake in D2.
