Single player?
 

I haven't read any setup guides or anything yet, before I do I was just wondering if someone could let me know if this is possible or not first.

I'm just wanting to experience a lot of the content I missed, so my idea is to have a bot group on my own emu server that I can edit and/or use GM commands to make 1 group raiding possible then progress through a lot of content from the last 5 or 6 expansions that I haven't experienced.

I'm looking for the experiences of the content, and skipping the level/aa/faction grinding.

in short - yes
keep in mind that a lot of raid content was build around properly geared 4-6 groups, so a single bot group would have to be either overgeared/overpowred or raids would have to be nerfed down a lot

There is no content completed past GoD at this time.
