Swapping Runeglaive's damage to physical was antipropedeutic in regards of spell/on-hit effects
People still don't understand that abilities are divided in spells, buffs, on-hits and autoattack replacers. Changing its damage to physical right when you bugfixed the Luden proc means that now people are conforted in their ridiculous thought that any magic damage thing scales with AP and procs Luden's while any physical damage thing scales with AD and procs BotRK.
