Obey = fairy auto casts embrace + you have full manual control.
Steady (after first summoning) = fairy auto casts embrace, but you have no control over her at all.
Steady (after obey/sic) = same as Obey
That uses obey on your current target, if it is an acceptable target, if not it will try your targets target, and if neither of those find a viable target, it will try for your focus target. Generally, if an enemy is not found in 1 of those 3 instances, then there are no enemies nearby or you are out of combat.
Having only <t> means you have to switch to a mob to gain manual control, instead of keeping the tank(s) targeted.
0.5 is fine sure. The only time I heel her is when everything is dead and we are moving to next area, so 1 sec isn't a big deal.
