While five minutes are underestimating the effort one has to spend to change a bunch of scripts on the server, including debugging, the upload and reload, it is indeed true that changing some numbers isn't a big deal, skill wise.
However - and here comes the usual however - development on the game server branch of development was stopped long ago. The new development branch, commonly denoted "VBU", has to be worked on with main priority in order not to delay the release more than necessary. And now comes the main point: At this moment, absolutely no developer found a single minute to work on magic. So, no one had the time to work on the development branch, so this "no one" won't have time to fix anything on the game server in addition.
It is not a joke that the developers ask for support on almost a weekly base. Lua scripting isn't hard to learn for anyone who understands this kind of code:
for i = 99, 2 do
write( i.." Bottles of beer on the wall, "..i.." bottles of beer." )
write( "Take one down and pass it around, "..(i-1).." bottles of beer on the wall." )
write( "1 Bottles of beer on the wall, 1 bottles of beer." )
write( "Take one down and pass it around, no more bottles of beer on the wall." )
write( "No more bottle of beer on the wall. No more bottles of beer... " )
write( "Go to the store and buy some more...99 bottles of beer." )
