Best class, skills, and class paths in your opinion for all units? (Including parent/child/spotpass units)

[Stwabeby]

I want to figure out the best classes and skills for all units (including child units and spotpass units, i.e. Emmeryn, Gangrel, etc.) based on strategy AND storyline (basically what's good for them gameplay-wise AND story-wise). Yes, I plan on getting all DLC and tackling Apotheosis. Any suggestions/help would be appreciated!
