I haven't seen anything wrong with the 'draw distance' and haven't noticed any real difference between other servers I've played on. Official RO only looks like it has a wider draw because the zoom is so horrible.
Increasing the draw distance is always an advantage for players. Hunters can already kill a monster like a Kasa on your average server before it gets close enough to use skills, just because of the DS range. Extra range means more free ranged shots against most monsters. I can't think of what NPCs are exploitable by being able to click them from farther away though. Also, think about what that means about ranged characters vs. non-ranged characters in WoE (assuming that WoE is a big enough thing here). Double Strafe and Falcon Assault have some of the largest ranges of attack in the game because of the way bows and Vulture's Eye work on ranged skills.
There would probably be a small increase on bandwidth used by the server, but I'm uncertain what effect that would have.
If convenience is acceptable, I may as well suggest adding a faster refiner for weapons/armor/ori/elu/etc.
