Dofus was about 7 dollars a month if you wanted access to the whole game, if this becomes p2p then I'm sure the price would be about the same. That is nothing compared to what most people pay for cash shop items. I would rather pay that small price and have a game free from a cash shop than having it ruined like how Ntreev completely ruined Trickster for me and for many others with their Myshop.
LaTale, Lunia, Trickster etc, they are f2p but to what extent? If you don't pay for cash shop items you are still missing out on the whole experience of the game, and you constantly have to compete with other players that have access to better things because they pay for it.
