Business view:
IMC will have revenue because players who can pay can job change to whatever that they feel like playing.
Player View:
Players who screw up can start over without having to grind from lv1.
Players who want to be fotm.
Players who want to try new stuff.
Sure we might see less of creativity or the much needed trend of healers/tanks because everybody wanna solo, so why not? It would be fair for those who don’t have time but have money, and those who have time but no money.
