invested? how?
new stream of possible subscribers? where? OP is clearly not interested in subscribing.
Tables turn? how? explain in detail.
(silly analog ignored)
F2P takes money OUT of game development, it takes money AWAY from the game, Why should Blizzard do this?
Exactly what in OPs plan would encourage anyone to subscribe?
Not enough 'long term' interest is subjective at best, Why do you believe Blizzard continues to release expansions? to feed the masses? No, they do it to feed the company coffers.
Decline perhaps, but nothing in OP's proposal prevents that, in fact by virtue of carrying more non-subscribers I would say it hastens that decline.
So I'll ask yet again, Explain what financial gain is there for Blizzard to even consider this?
