I think, Bitcoin doesn't needs any change in it. But, if still need change something, sure I'll choose transaction without fees (even for a big transaction) and increase the the number of Bitcoins can be mined!
If there is no fee then the network would be abused too much, and the miners later will not have profit to run their mining rigs.
