Fire Emblem is a difficult series, I don't know if you guys have heard

Yeah let's not turn this into a "post picture of anime girls" thread.

Are prepromotes in Path of Radiance and Radiant Dawn as generally non-useful as in FE7? The only prepromotes in this game that I find really useful are Harken and Jaffar.

Pre-promotes in almost any Fire Emblem game are bad. 

However Radiant Dawn has 3 tiers so pre-promotes are only skipping 1 tier of levels and have plenty of time to catch up.  Plus once you get into the later portions of the game, almost every unit you get is pre-promoted.
