Steam seems to have proven that making games cheaper nets more profit so why not try the same for subs? Make an MMO that is more original and charge £5 a month and I would be much more likely to play it.
OK, you have a point and I should probably amend my answer to the OP.
Yes, you are right EVE survives as a sub based MMO, but that is because it is pretty much unique. Add 10-15 similar games, out of which 10 are f2p and you will see things changing dramatically. EVE is basically in the same position as WoW was when it started, it has the market to itself. Why does it have the market all for itself after so many years? Because it's a niche market and those don't attract much competition.
Your second point could also be valid ... although it raises the question of "how much is enough?". We were asked to pay subs so the devs could continue creating content. 15 euros, multiplied by God knows how many WoW accounts are active, gives you a pile of money, hence you can deliver the promised content. 5 euros, for a much smaller player base ... will it be enough?
