There was a night back in the mid 90s my gaming group was doing our thing, playing Magic until the wee hours of dawn when it occurred to us that we all had full-sized three ring binders stuffed full of printed errata that we had to have to play the game. It was not a fun realization and likely contributed to the downfall of that game's primacy with our circle.
While I do not think this new shiny FAQ for Mage Wars is the same thing exactly, it does give me a bad vibe that one expansion in there is now a host of actual rule changes, card changes, and errata piling up to play the game.
Some of that is simply unavoidable as the designers innovate and add new systems to the game, and I not only understand that but welcome it. However... I echo Sausageman's request for some way to get this info on the cards themselves to keep the game easy to play and teach. Nothing kills a new player's interest more than trying to learn a game and constantly having their understanding of the game upset with seemingly random rules lawyering read from some dubious print out or web forum.
