Were the changes in skills, especially the change of cross class to role skills, made with only group players in mind?

Some cross class skills were useful for solo play that would not normally fit the "normal" role of that class. Such an example is that Thaumaturge was able to acquire Protect and Cure using cross-class skills before and is now no longer able to. While this may not be "meta" for group play, it (and other non-role skill choices) were useful for newer players soloing through quests. Is there a chance that some of the past non-role skill configuration may come back?
