I really hope that Bungie adds more ability nodes (Attunements/Ways/Codes) for each subclass in the DLC! The silver lining with these ability nodes is they give Bungie more freedom to add experimental abilities without breaking overall balance, since they're isolated to their own node. The major downside is that there are only two choices per subclass! Bungie, please add more ability nodes in future DLC! Also, we need better short-hand for these things. Skill trees? Nodes? Clusters?
