HAHAHAAHAH nexon... nexon..

tried the leech system on a 95 paladin with a 120 cygnus, not really worth it compared to training (for me)

but i took a 1 min vid of the sidekick training my level 40 pirate, and dear god... gimme a while to upload it (lolfraps massive weight.)

Exactly, it just makes the pre 3rd job levels faster but the main idea of this is to allow non leechers to leech when they party with eachother.
Example: level 90 and 82 grinds at lvl 93 mobs, level 82 cant leech obviously but now he can. But the fact that the kill exp isnt reduced at all seems a little odd to me, imagine lvl 110-120 at lhc with that..
