Finding it detestable matters to me, its the reason I posted at all to you, duh. May not matter to you or anyone else but its still extremely relevant to this scuffle.
Zoning is a mid lane control mages job, they don't magically become something totally different by occupying a different spot on the map. As in lux is still being lux, a long range bursty mage, no matter where she is doing it with what resources.
Supports have kits where each part is more a benefit to facilitating team members success rather then their own. They do very well on little gold and also benefit way less then other champions would on a lot of gold. These are supports, not one such as Lux that are totally self sufficient to carry a game and others benefiting form her root and shield(a pathetic amount of team oriented kit to designate her a support) is secondary to the amount it benefits her and her natural combo of damage she will do thanks to them.
Thresh, lulu, sona, allistar, rakan, Leona, blitz crank, ect. are champions whose kits are way less effective being used solo then if they have team members to utilize them, as in their contribution is way higher with more people around. Lux and brand can out put the same effect regardless of whether or not they passively assist others. You do realize lux in bot lane does what lux in mid lane does minus csing right? There is no other reason, "support" as a class isn't famously noted in the history of games as being "those that don't cs", like seriously think about it.
