Does this spells the end of leechers?

I think it's fine if a low level character leeches a higher level one. It's natural to want to help friends level faster. It's just when a low level character trains twice as fast as normally possible in a party by hanging afk on a rope while the high level character kills things that something is a little broken. The new system seems to correct this, as lower levelled characters leech less exp from the party than high levelled characters, and the total leeched exp is much less than the exp gained from killing.

Or when a person watches someone kill an anego or BF and they gain 199% off it.
