RO's engine is just, so, so bad. Even for a 2002 game. Which is partially why trying to change it heavily can be just a big waste of effort.
In general, yeah, trying to fix so many of the game's flaws is a noble goal. Sadly, most players don't seem to think that, as they feel alienated by most custom changes. It doesn't help that most custom features I see in servers don't actually make the game better.
