They are talking about doing a level squish in retail? I hadn’t heard that (although I wouldn’t be entirely against that truth be told depending on how they implement it).
As far as leveling goes, heck you don’t even have to travel to questing zones. If you want just level a class that can tank and get instant queues for 5 mans forever and ever. You can literally sit in SW or Org for 48 hrs /played and have all the money and gear you’ll ever need and probably be lvl 110 at least. These last 2 days I’ve started playing Al again, he was 93 (I think) two days ago. I play for maybe 1 1/2 -2 hrs a day. I’ve done nothing but BG’s and dungeons and I’ve gained like 3-4 levels or something like that? All without ever leaving SW.
