a vet is probably a bit more "complicated" to set up initially but will be less complicated down the line because you wont have to worry about organizing games. Sure, you gotta wait for your account to go inactive but now is the time to do that. Buy a month, gear up, buy a bunch of spare gems and enchant scrolls (like seriously, double stacks of spares here) and whatever consumes you may want. But keep in mind that garrison can get you drums, we have access to glider tinker so you wont need those, Alchemist flask is still bis, etc so you wont need to stock up on much.
Once youve done all that, you can let your sub expire and enjoy casual BGs all day every day. Super simple.
