Greyhawk will evolve greatly with a new story arc, probably taking 3-6 adventures with a Sandstorm arc.
Additionally there are 3 intro mods a year, and not only is this a great way for new authors to get a chance to submit alongside the big shots, but it entices players to make new t00ns, rather waste a slot a big con. (I apologize for that jargonasm)
My point... people will continue to create new characters fairly often, whether due to TU shortage, fear or water adventures, desire to play in new regions, etc.
so these feats may get some use on people's RP-characters, or their experimental characters etc.
beyond that... who knows.
I'm just sad the Oozemaster disappears March 1st. He was so misunderstood :(
