I just recently watched a video by Rossboomsocks where he built 
on 
. This actually allowed the passive of the and to both trigger.
Is this a bug or the actual way it is suppose to work. It seemed to be completely ridiculous from the increase and I would love to try it.
I think its more of an oversight with UNIQUE passives, unique passives only prevent you from stacking the same item for an increased effect.
I'm guessing that the upgrade is technically a different item so unless riot decides to change it to a NAMED unique effect then it aint a bug....... just a really dumb balance oversight.
In other word its probably functioning as how buying 
and
would give you 20% cdr but two would only give you 10%
So would that work if Ornn had a Sunfire cape and the upgraded Sunfire Cape? Would the AOE dmg stack?
its such a niche and situational build that I don't see a balance problem. Makes Ornn viable outside of laning phase. Better then getting chain cc and gun down as a melee champion.
Lol imagine that on vayne though.
