Ok i hope this isn't a repost.
It really sucks that when you want to lvl a new char and at the beginning someone on lvl 70 Helps you, you gain just like 12 EP for one NPC.
So the only thing you have to do to change this is getting a lvl partner which is a hunter on a high lvl (normally 70^^ )
Then search for a good grind spot i will take for example the instance called Deadmines.
Now at first clear the first room so that youve got enough space for your low char and the pet then the hunter has to take control over his pet and move forward to one point where the pet would normally desspawn, when you kill now NPC's with the Pet that far away from the main hunter, the low char gets full EP for example the elite NPC's in deadmines gain about 300-400 EP.
Because the mobs there are really low you can kill a lot of them in the less 55 seconds you have until the hunter has to recall the pet and take controll again.
Like that you can clear the whole instance.
Thats the only point which sucks that you have to recall the pet after 60 seconds, but its a really cool trick to power level from 1-30 !!
Ok I've made some simpel pictures to explain it a little bit better(I'm sry i havent got any screen which proofs that you gain all the ep but believe me it works ! )
