Cadfan said:The bold portion would be the key quote. And it goes further than that. Every bit of information we have so far indicates to us that 60/40 is not a good way to measure 4e multiclassing.
In short, Multiclass A/B is NOT the same as Multiclass B/A in 4e. Not in the sense that one is disadvantaged in comparison to the other, or that either A or B is a better place to start, but rather in the sense that they are simply not the same thing at all and comparing them is an apple to oranges comparison.
60/40 or any X/Y doesn't mean X levels of A and Y levels of B. It is a measure of how many of the abilities a character has come from A and how many come from B. In a 60/40 split a character with 5 abilities has 3 from A and 2 from B. With 10 abilities that is 6 and 4.
In other words, it is a measure of percentages, not of levels.
As for the rest, assuming that a "most reasonable" result of multiclassing is that 1/4 to 1/3 of one's total abilities derived from feats+class abilities come from "class B" then I am of course fine with A/B being different than B/A. My point is that if feat-based multiclassing can achieve a state where the total number of abilities one has come 50% from A and 50% from B that it should absolutely not matter if you started A and added B or started B and added A.
