Rotom-a has its own uses and is very good overall. However, you can't say gengar has disappeared (or has been outclassed by rotom) while it is still sitting at spot #12, although as I understand this was a dramatic decrease.
Rotom primarilly outclassed all of the bulky ghosts; if you want an offensive sweeper most people still (as the stats prove) turn to gengar and it's 24 greater base speed and 25 greater base special attack.
Rats, my earlier post shows you what I know for being a Wifi "purist". . .

Thanks for correcting me. Better Speed and Special Attack would help Gengar's case drastically. Dusknoir, for the record, is still the bulky Ghost of choice on Wifi, though he does have the niches of being physically oriented and possessing Gravity even when Rotom is present.
