Coins are here for bring innovation, and there is no innovation in changing some parameters and make an altcoin just for changing values - or even worse, by inputing some values in a site and pooping a new coin.
Most altcoins are dead or dying because people started to realize that, even Litecoin is dying, why do you think that your newly created copy-coin will survive? The profit time for pump and dump copy-scam coin creators is over.
You are pretending there is no group of 2-10 friends out there that wants a coin just for them that might get big one day.
You don't think the coingen tag will prevent it from getting big anyway? It's like websites with "weebly" in the url lol.. just has such a stigma, whether warranted or not can't change anything sadly, in my opinion..
