Collision detection: Envirnoment and Monsters

[Elexia]

Wasn't it removed primarily because JP players didnt like bumping into people in the market wards (even though that was never an apparent issue to me)? So now that we no longer even use those market wards, basically, can we have collision detection between players/monsters back?

Actually, I've seen more complaints from NA/EU players about not being able to run through monsters or other players and it was "retarded that you can't."
