Please make SMN rotation less rigid. Also, Sustain

[Pyitoechito]

Change Aetherflow so you can have both 3 Aethertrail and 3 Aetherflow stacks at the same time.

I feel that's less about rigidity and more about punishment reduction. You're only going to have overlapping Aetherflow and Aethertrail when you miss an AF skill and have to wait for another Aetherflow to get the last bit of Aethertrail (pushing back DWT and Bahamut). Having the Aethertrails not block Aetherflows is a good way to reduce the punishment, but it might help more if Aethertrail Attunement always procs on an AF skill regardless of if it affects the target (eliminating the hard punishment of having to wait for the next Aetherflow to enter DWT).

Also, give us the ability to Rouse Bahamut. I feel as if too many things get 'locked out' depending on where you are in the rotation.

I feel like that would only make the rotation more Rigid as well as a straight up buff. If this was the case, players would ALWAYS want to use Rouse for Bahamut to maximize damage (and the 40% increase would be incredibly substantial).

Also, please restore Sustain. I feel as if there was no need to remove it, it makes pet health management impossible.

To reduce bloat, it could be attached to Physick as a trait that grants the Sustain effect when cast on your personal pet. Or they could just have Physick scale with INT instead of feeling like an incredibly low potency heal.

Sometimes when you cast Ruin III you can get Ruin IV.

"Further Ruin" (Ruin IV proc) actually procs on pet skills and not Ruin III casts.
