Now if you're saying "why is this guy insisting we put more Call of Duty stuff in everything when that's already happening everywhere else" bear with me. I don't play CoD multiplayer at all (not a big FPS fan) but the prestige system in it has always fascinated me. Prestiging in CoD means hitting the level cap then electing to start over at square (or level) one all over again. I think this could solve a number of issues such as:
-not enough players doing mid-level content to form a party; theoretically players would continuously be doing all content
-being forced to make early levelling super super fast to sell expansions that have later-level content; with this new expansion content could be of all levels. This is of particular interest because of the response to Cataclysm in which despite Blizzard creating new low level content by essentially setting the world on fire and replacing all the starting zones, led to a lot of players not sticking around because they were only interested in high level content because that was where their character was at.
-it could also encourage players to play more hours and subscribe longer?
I'm not crazy am I? If there are any game-breaking issues lemme know, 'cause it's seems like an obvious money printing feature and I don't know why they're not implementing it.
