I have searched for a bunch of different keywords but i couldnt quite find something like it. You might want to label it common knowledge but i bought powerleveling to 70 a while ago and had i only thought about this then i'd have a second level 70 now.
Hopefully others wont make the same mistake i have. If it's a repost then im sorry but i couldnt find anything adressing this perticular idea.
Well it's simple. The RAF program gives you 3xExp and whatnot? Ok we dont really care if the powerleveling service does it 3 times as fast (ok perhaps but still, not the point)
Now to the interesting part, for every level your recruit gets - you get 1 to add to an existing character below it's level, right?
Now if you had your mind set on purchasing powerleveling service you should make an RAF acc, upgrade it with Vanilla WoW + BC, buy 1 month of playing time (should easily be sufficient) then hand that over to the powerleveling service.
My idea here is that if you have the same name on the new account (or perhaps same last name, which i think would work) you can add 68 or 69 levels to your own account then just transfer the new level 70 over to your original one. Then you could either keep the new account or sell it, whichever you feel like.
For a total cost of 30-35$ (WoW+BC), 15$ (Subscription) and 20$ (Transfer fee)
65-70$ extra is easily worth it for a free level 69 character, isnt it?
Besides your old account gets a free month of gametime so basicly its only 50-55$ for a extra character up to level 69 and a blank wow acc.
Hope this helped someone!
Crucial note: This of course depends on how much powerleveling you bought. IE if you buy powerleveling on a 30 level span you'll only get 29 or 30 levels to your level 1 character.
EDIT: Combine this by leveling the level 1 character, on the original account, as close to level 2 as possible without actually getting level 2 and you'll easily be 70 once the powerleveling is done!
