A Noxian Support champion?
After reading the new Noxian lore and remembering Taliyah's background story I find it odd that we dont have as of yet a Noxian support. Basically as it says on the page "As Noxus expands and defeats neighboring cultures and cities, it offers the conquered people a choice; swear loyalty to Noxus and be judged solely on your worth, or be destroyed. This is not subterfuge or any kind of ruse; the Noxians are as good as their word, and many who have embraced their conquerors' way of life find their prospects greatly improved. But those who refuse to bend the knee are crushed without mercy".
This compared to their previous lore would suggest that Noxus would see the strength in healing, shielding, buffing etc their troops as it would greatly benefit their goals of conquest. This support champion could of joined them willingly or unwillingly like Taliyah. I think it would be great to have another "evil" support as really only Thresh stands out and perhaps Lulu. They don't even necessarily have to be "evil" as they could have been forced to serve Noxus.
On the other hand Noxus could have a support Blood mage/priest , stealing enemies hp and giving it to an ally etc, or a " Master tactician" which would buff allies and could help lay siege to towers etc (Think of like a back line general). The Master tactician route would free up Swain to "just morph and eat them." as riot has said in the past his title and his core game play do contrast with each other a bit too much.
I believe it would provide another dimension to Noxus as it is mostly just humans with sharp blades at the moment and would also fill a gap in the nastier side of League's support champions. Also would make having a five man Noxian team easier for those epic battles against Demacia.
