Why is this still a thing? We get it, dragons synergies in this game make you immune to magic damage, do you really need that to translate into the pve dragon being pretty much immune to magic damage? With the upcoming change of dragon always dropping an item, this def needs to be looked into.
you can still do it, you just gotta make one of the mages ad focused and keep them alive....IE some good examples of this are going attack speed and AD on Lulu, or kassadin since their not benefitted by magic items at all
I've never had problems killing a Dragon with Mages unless the Dragon had Warmogs or a Dragon's Tooth. Dragon does NOT have inherent Magic immunity. He's also weak to CC which mages have a lot of. I have more trouble with Gunslingers vs Dragon than mages, because although Gunslingers rule large team pvp, they lack CC and just face tank all the Drake's damage.
If you're talking about Shyvana/Aurelian...... they ARE killable by mages; the challenge is what items they built vs what you built.
I've dueled a 3 star Shyvana for an entire combat encounter because it had 
. Unfortunately for that round, I didn't have Grievous wounds/it died early, so after about 10% HP Shyvana just stayed idle and kept gaining back enough to survive.
Keep in mind mages still do on hit damage.
P.S. Some Sorcerers use AD items all the time in TFT..... Lulu builds SoS Ahri builds SoS
