After my main account getting banned, I bought the expansions from that Christmas offer and went right to 85 in a few days. My druid used to have 13.6k achievement points which I've saved up from the release of the system at the end of BC. In the start of Cata I was around 8k achievements and until November 15th or so, I went from 8k to 13.6k just by putting my mind to it.
I never had this done before, but I've been part of guilds that sell old content kills/titles/misc achievements for gold. Does your guild sell achievements?
Anywhere from 5 man instances (Cata of course) to a full Cata raid content clear. Gold has never been an issue and I acquire it at a good rate, good enough to pay big tons if the deal is nice.
So the question is TL;DR,
Does your guild sell achievements for gold? If so, post here please so I can pick up some!
No faction/server preference. Will transfer.
