Firstly, no, not suggested for Pathfinder. For Pathfinder, you keep the ToB classes exactly as they are, and increase the HD for Crusader to d12. Why would you nerf a Pathfinder class? You'd be stupid to do that.
Second, nothing is official errata because the errata wasn't properly released. These are from Richard Baker himself. As I said, you want to dispute it, you take it up with Richard himself. All the power to you.
I'm just the messenger. No need to shoot me.
EDIT: I'd like to further add that even if you did except it as official errata, 99% of everyone here would just house rule it back to what it was anyways.
If Baker regrets ToB because it means he created a class that utterly and completely out-shines a Fighter, then Baker can go blow himself for all I care. Tell me when he nerfs Wizards, Sorcerers, Clerics, Druids, Psions, Ardents, Erudites, Favored Souls, Bards, Barbarians, Warlocks, Knights, Rangers, Scouts, Rogues, Dragon Shamans, Dragonfire Adepts, Ninjas, Spellthieves, Monks, Hexblades, Swashbucklers, Wu Jen, Shugenja, Warmages, Beguilers, Duskblades, Archivists, Dread Necromancers, Spirit Shamans, and Factotums. When he does that, then I might think he's actually serious about game balance.
