I have no knowledge of War Hammer, but to me the prestige classes always resembled something in the RM2 book, Arms Companion.
Tweet points out that the real ancestor of the PrC is the Rune Lord and Rune Priest from
Runequest (1978). Though a classless system, both of these were basically "prestige" roles that required a PC meet certain prerequisites (both mechanically and RP) before entering.
However, according to Tweet, it was Monte who actually came up with the PrC concept, so there may be a RM connection.
And, not to be snarky, but I'm hesitant to credit RM with much influence, simply because I remember when RM was basically a set of rules-add-ons for AD&D, and that the basic "model" of RM is the D&D model. Most of what RM could contribute can possibly be seen as nascent in D&D to begin with.
Not to mention, the basic mechanic behind d20 --d20+mods >= target number-- is basically how combat has been resolved in D&D since 1974.
d20 draws on a lot of influences in a lot of major and minor ways. Pointing to any one system and claiming d20 is somehow a "ripoff" (something I often see people doing with their pet system of choice) is pretty silly, IMO. d20 seems to simply have found (or at least resemble) a lot of good ideas from all over the place and combined them into an excellent whole.
