Well doesn't /home, /warp and similiar plugins also destroy the concept of "survival"?

I personally don't agree that they are on "creative-mode", just because they have infinite money.

They spend a lot of time and effort in building those farms, where they could have been farming dungeon, killing mobs or collecting ore.
But instead chose to invest their money, which they initially made through some farming, to put farms together with some ingenuity. (Which is also is a very monotone job, building row after row of melons and pistons. just melons and pistons.)

Nevertheless i agree with slowing it down a bit.
