I'm actually pretty happy with EoS and how it works. EoS does her job of embracing at will, while I still control her other abilities when needed. Sure she might decide to heal unfortunate DPS or the same target I'm focusing, but for me overhealing is not that much an issue as I primarily use adlo and it still applies galvanize to the target for extra layer of protection. Usually tank "should" be at lowest HP anyway, so my EoS usually focuses the tank with me, and if that's not the case I like the fact that EoS restores injured DPS to safe levels, leaving me more room to do my things (primarily focusing more on tank or dpsing).
