Hello, I had a very similar problem when I came back to WotLK after a long break and did not want to spend evenings tuning macros again. For Sirus private servers, Byster with WoW Bot 3.3.5a Sirus can be a practical option, especially if you need autorotation rather than a huge complicated setup. What I liked is that it covers PvE, PvP and utility roles, reacts to priorities and boss phases, and has things like auto-buff, aoe and solo modes. I would still start carefully, test one class first, and avoid turning everything on at once. That way you understand how it behaves and can keep your playstyle natural.
