For the most part, yes. This is especially true for those that are Villagers, since they get an additional 10 levels or so as their smaller class, though I'm not certain if they kept that class in Echoes. However, the ones that do not get a third tier promotion still have their uses. They are either the protagonist classes, which often can get p damn good stats or a really powerful weapon to make up for it, or the magic classes, which are always useful in some way. Still use the second tier capped classes, but have your front lines be the third tiers.
