Scaling in Heroics bugged?

Akari

Right now in this Juggernaut Heroic, my highest character is a 293 Beast, then 262 Doom and 262 Torch (Last I heard they use top 3 for scaling but if it's top 5, my next are 230s). The second hardest node in the sub is level 306/316 (varies), and the hardest node is 325, Deadly difficulty. I can only assume that this scaling is based on my full roster, and not my limited Heroic roster. I won't question the terrible character choices, I just want these nodes to be manageable levels and not higher than any character I have. You did this in the EOTS test where the levels went far and beyond my roster even with unboosted 5* (my highest is 360, the nodes went to 400ish), and it was a horridly painful experience. Please adjust this at some point.
