Who on earth designed the Paladin of Cuiraécen? Unless the table is incorrectly written, it seems that you get four or five abilities at 1st-level (nearly half of all the class abilities except bonus feats). This creates a huge problem for people cherry-picking the class. The multi-classing restriction is worthless if you consider that you're getting nearly half the class as a simple one-level prestige-class for CG clerics of Cuiraéecen.
