Psion said:I'm not seeing why the alternate class abilities is in any way a simplification of substitution levels. They are the same thing. It's just that substitution levels plug into the existing structure and (perhaps more importantly), they are associated into sets allowing a DM to better define what is permissible or desirable in a campaign. SLs are easier to manage AFAIAC.
I think the greater long term benefits of the alternate class features lies in their broader use. A substitution level is a fixed point in a level progression for a specific class, while an alternate class feature is a replacement for a class feature that may be shared by a number of classes.
In addition, the simplicity is fairly obvious - all you're doing is replacing an existing class feature with another. You're not concerned with a table, class skills, hit dice, skill points, saving throws, etc. It's a more straighfoward presentation of the same basic idea.
