The danger for this, is if the game is not expanding the player base and lands make summoners even more expensive for new players with cost of entry now pushed up even higher we may end up losing players and it will not be healthy.
What we may end up is less value among less people.
It's all a risk I know!
But people can go crazy for this kind of LAND stuff, at least in the short term, it's just a matter of being bold enough to capitalise on it at the right time!
