[Xerath Bot] Not casting spells

I ended up laning against a Xerath bot and he was only casting his stun. He would charge his Q but no cast it, I never saw him cast his AoE, His ult would simply root him and show the range but he would never cast. *Repro Steps*: --Play a Bot game on Summoners Rift (alternatively you can do custom game and set Xerath as an opponent) --Choose any Champ --Play --Magically get Xerath as an opponent and get hella easy kills
