So what you're saying is that basically, SE is screwed either way. If they make it hard enough to lock out the casuals, they will lose them to another MMO. If they don't make it hard enough, they'll lose the hardcore to another MMO. And even if they did make it harder or have more content, the hardcore crowd would likely still finish it before more content was ready and still unsub, leaving SE with few customers. This is the root of the issue; SE is playing it safe by trying to meet both crowds halfway.
