yes, i am disagreeing with you on saying that Disruptors is the same role as Tank

a Tank uses their body and CC to prevent the opponent from killing their carries

a Disruptor uses spell-created terrain (Anivia and Taliyah's walls), ground based damage (Anivia and Zyra's ults, Morg's W), or they set up an area that the opponent cannot cross without taking major damage (Ori's ball, Heimer and Zyra's gun nests, Teemo's shrooms) to block off areas from the opponent. Also, it seems that most/all of them need time to set up their area denial and can't just jump into fights. (Honestly, Shaco and maybe Maokai should be in this group as well, honestly)

Tank is character denial, Disruptor is area denial. Leona is not a Disruptor of the kind described by Riot AT ALL. Maybe the name isn't great for reflecting that, but eh...
