I main scholar and i suggest to control Eos even if its to a low degree, if you want to be a more "Effective" scholar. Personally I have her abilities on hotbar and macro. Also Im not just talking about group settings even in solo missions it helps to take control. I use here to lure monsters out of the way if they are going to slow me down for a mission or make her gain hate by making her heal while I wait for a moment. I know lots of people say dont worry about using her in early dungeons and they are partly right but why wait for the harder battles to learn to control her when you can get the hang of it in the easier dungeons.
