So, there've been other threads like this but I like thinking about it. Imagine if you could replace the core classes with the same number of classes, but balanced. If you were going to do so, how would you do it? The goal is not just balance... you should also be able to make similar character types. Here's my new list, along with what they replace:
Ranger (add in Wild Shape Ranger variant, replaces Druid as well)
Factotum (Replaces Rogue and Wizard)
Swordsage (along with Unarmed variant, replaces Monk)
Crusader (Replaces Paladin and Cleric)
Warblade (Replaces Fighter and Barbarian)
Warmage, Beguiler, Dread Necromancer, Warlock (Replace Sorcerer)
Bard (Stays in as a core class)
Binder (Added in as a new concept, sort of replaces Druid as a magical fighty jack of all trades type)
All of these should be reasonably balanced compared to each other. Obviously, some of the replacements are much weaker than the originals (Factotum replacing Wizard, Crusader replacing Cleric, Wild Shape Ranger replacing Druid) and some are much stronger (Swordsage replacing Monk) but the overall effect should allow for very similar character concepts while adding some new ones. There's also multiple options for everything... if you need a trapfinder, you can use Factotum or Beguiler. If you need skillmonkeys in general, there's plenty of those. Crusaders or Binders can be healers (Factotums sort of can as well).
Also, these classes are a lot more beginner friendly. Gone are classes like the Fighter and Sorcerer where you can screw up the allocation of your class features early in your career and be relatively stuck with those choices. Plus, other than a few things on the Factotum list and some advanced learning options, all the really broken spells are basically out. Fun. Anyway... thoughts?
