Is there a better way to level?

Zakum leech might work if you have EoFs and someone that kills Zakum in seconds. I've never tried it though so idk how fast that is.

As much as people may frown upon something like this, i'm thinking I might give it a shot. My main complaint is that I don't wanna spend more than 5-6 hours leveling my link skill MULES to 120 when I would rather spend as much time as possible on my main you know? Also, I played well before big bang, and had 3 chars over lvl 150 in 2008 so I know how it used to be, I just thought Nexon had evolved past the point of grinding ass all day
