Hey,
Similar situation. I was banned in banwave.
Took a while to regroup, do some IRL stuff. The itch came back, and I wanted to return to WoW safe as possible. Considered my options. I sent an RAF from my original Bnet#1 (WOW4) to a new email and registered a new Bnet#2 under the same names. This is so I can (long term plan) eventually transfer my main from Bnet#2@WOW1 to Bnet#1@WOW1 (Banned) in November when the suspension expires.
My only intention this time around is to see out the Patch, do my Garrison and continue Raiding. I was a Mythic tank and as such I really miss the scene. I'm not going to invest my time into PvE as I did, but thus far I have RAF botted to about 60. Then I boosted via WoD to level 90 and botted about 80% of Questing to 100, solo. For the remaining 20% I botted using Enyo and TuanHa Special Edition. I am now Raiding and progressing my Garrisons. I have no intention of botting my professions or Garrison.
So far, all good!
Best of luck with your progress!
