You were posting an example without a thesis. I responded to the actual thesis. In no way did you contradict the "Neither Dabbler nor Mashup" in the block-o-text.
I most certainly did give you a thesis while contradicting you- the PC entering the Cleric profession in 3.X is a fully capable member of both classes (in the context of his levels), wheras the 4Ed PC is not (he's not a spellcaster or divine channeller- IMHO, quintessential abilities for clerics).
(Upon further thought, I suppose we could have a differing definition of "mashup.")
Why would I make him a BattleSorc or WarMage to gain abilities that I don't need?
I was illustrating that its possible to do
that PC style within 3.X, after pointing out some PC types are not possible in 4Ed.
Someone who profoundly changes his life probably does have his primary skillset atrophy with time, but he doesn't lose everything completely.
Then HE DIDN'T MAKE A COMPLETE CHANGE THEN, DID HE? He's a dabbler by any other name.
So a person who disavows his former life to become something else has to forget everything about his former life in order to make a complete change, then?
I personally know at least a few soldiers who are now Catholic monks who would beg to differ.
So would historical figures like St. Paul, St. Francis of Assissi, St. Katherine Drexel, Siddhartha Gautama, Cat Stevens, Audie Murphy, Andrew Carnagie and Brian May, who all made significant life changes (albeit not neccessarily into a more religious lifestyle).
And even if they are, 4Ed doesn't support the PC who "dabbled" first- especially in a variety of fields- before finding his true calling.
3e doesn't support life-changing career changes, either, unless your new career just happens to synergize with your old one. Sure, you can abandon being a fighter and start advancing as a wizard, but there are a couple of problems.
Again, I don't care about synergy- someone who splits his time between warcraft and spellcraft will eventually suffer in comparison to one who focuses on one or the other.
That said, it does it much better than 4Ed does.
Assume, arguendo, that Intense_Interest is right an you have to abandon warcraft to adopt spellcraft (for example) in order to simulate a life changing career.
In 3.X, you simply stop leveling in the former class- the XP penalty (if the DM enforces it), simply reflects your later start in the new field. (Michal Jordan never did master baseball).
In 4Ed, your primary class is your primary class forever, barring retraining rules...which are also available in 3.X.
