The game is so slow paced in classic you really don't need any automation, or macros, unless you're planning to AFK farm or really don't want to do any work.
I personally made the same move, did not want to deal with the queues and general toxicity I saw on Aradune and moved to a 6 box on Riz.
I have one character that is dedicated to be the pilot toon and I dish out commands as needed from there. Hotkey for melee to assist, heals, nukes etc. Can just focus on that one character and MQ2Cast and Melee take care of the rest. I will use KissAssist just to do buffs from time to time. But that's just so I'm not monitoring them. Not entirely needed. Pilot method works very well though. I've generally been able to handle anything and once your comfort level increases you'll work out ways to handle those "o shit" situations.
You're always going to have people perma farming the high profile camps. Efreeti, and Frenzy as another poster suggested. I think you're going to find a similar experience on either server. One it's just easier to do, but people will find a way on Aradune.
