In the
Future of D&D seminar they said that each class would have a 'multiclass table' that ramps you up to the full power of the class.
The multiclass tables sound interesting. I hope they aren't too different from the main classes, as we don't want them introducing too much complexity.
One thing I'd always wondered about was if it would be possible to accomplish a similar thing by feats? The multiclass tables are an attempt to stop "level-dipping", which is an attractive strategy because classes have to be "front-loaded" at level one so that you feel like you are playing something different and unique from the get-go. That means level one of each class is comparatively better than other levels of that class, and so we get the problem.
What if all that front-loaded stuff at level one was feats? So, for instance, a level one wizard just gets his spell book and cantrips, Arcane knowledge and level 1 spell slots are bonus feats.
When you choose a class at character level one, you get all the associated bonus feats for free. Thus a level one wizard would look the same as he currently does.
A rogue who multiclasses wizard, however, doesn't get those bonus feats unless he buys them as normal. So his multiclass dip doesn't reward him disproportionately. He can eventually build up to the same power that a pure wizard got from level one, but he has to spend feats to do it. He can also continue to level in wizard and ignore the bonus feats, meaning that his multiclass wizard will be a slightly watered down version of the class that nonetheless gets the full benefits from its later levels.
I do like the idea of multiclassing at 6th level and getting the 6th level benefit of whatever class you're dipping into. I don't know how that would interact with what I just talked about, if at all.
