Best combination for leeching?

That would be bullcrap, so either you've got no clue or you're lying to yourself.

There's nothing to do at a higher level that isn't the exact same as at lower levels.
You either kill stuff to level, kill stuff to try to get an item that will take forever, kill stuff to make money to do things you want to do that will run out much faster than you can make it or kill stuff because it's what the cool people are doing and you think it will make you cool to do it too.

It's all killing. It's all grinding.
There's no level high enough to make that go away. Even at 200 if you want something you've got to grind for it, or you've got to merchant your ass off which is just another form of grinding, and lets face it, that doesn't even require a level over 16 to do so being high level again has no value.

I really couldn't care what other people think. I don't enjoy grinding with a low level char. skills are more interesting and characters look better at high levels. Hell on my DK I used a 7x PA till 110 because I like the way it looks. its just like playing an offline game. the gameplay in Devil May Cry and in Bayonetta might be identical but I find DMC alot more interesting because of character design.

I played maple for years and I know what it's about.

Anyways I don't want to argue. I just wanted to get some information about leeching and if what dpeterlin says is true then I'd like to know how leveling got that much faster. at 9x leeching at harps I could do a level in an hour. Am I to belive that now you can level in under an hour at 9x?
