As someone who has been playing SCH for a few weeks now, to take a break from my DRG, I can say that I haven't really had many issues with my pet, honestly. I have obey, place, heel, and Fey Illumination on my first hotbar with most of my DOTs. I'll usually pop a Fey Illumination during a heavy pull or boss fight, then I can immediately switch to obey and have her go back to embracing party members.

If I don't do that, she will just spam her other party abilities, which is generally fine since they help anyway. My SCH is only 44 at the moment, so I can't speak for the likes of Coil, but pet managing really isn't as bad as it sounds. The only time I have a derp moment with a pet is sometimes when I place it during a boss fight, then forget to heel it when we're running off to the next area and it withdraws from the field due to the distance created, lol.

Other than that, it's not an issue. As for the DPS getting hurt with the tank... Again, generally not an issue. I'll simply use Physick on the DPS, then probably put Aldoquium back on the tank by then. If the party itself is hurt, I'll use Succor to give myself enough time to prioritize healing.

So yeah, I'm fine with the way the system currently is. It sounds more like a personal issue, honestly.
