I'm following it. I just haven't had time to think about things in any depth.
I like THB/ryryguy's idea, but I do think there should be some class that can take multiple weapon training feats the way the bard can take multiple multiclasses. I'm tempted to open them up to anyone but say that martial classes can take multiple weapon training, except that might make these too common.
Quite honestly... unless I'm missing some kind of weird loophole or building trick that I haven't thought of yet (and I'm sure there's a ton of them), I don't really see how any class could really abuse having tons of weapon training feats. Sure, you're proficient at using 3 different types of superior weapons... but you only have the ability to use (at maximum) two at a time... and that's if they are one handed. So congratulations, you can wield a bastard sword and a whip. But what about that bola/blowgun/garrote/spiked chain? You can only really get good by focusing on a particular weapon (on a mechanical standpoint), so I don't see why anyone should be restricted from having proficiency in more than one of these, even if they are the special "training/multiclass" weapon feats. If I'm not mistaken, even the power swap feats that come after the training feats require you to wield the particular weapon it was meant for while using the power, so again, no harm.
Am I missing something?
