Sion's Decimating Smash and Unstoppable Onslaught stop working in ARAM
I've played two games within the past 2 weeks as Sion in ARAM. For the first half of the game, his Decimating Smash (Q) and Unstoppable Onslaught (R) work normally along with his other skills.
However, about one-third;s of the way into the game, both of these abilities stop working and I unfortunately have to continue playing using only his Soul Furnace (W) and Roar of the Slayer (E) skills. This of course leads to a disadvantage in the game, resulting with only being able to inflict damage through auto-attacking, using his shield, and his shout.
It makes the game feel one-sided, with the other team being able to spam all of their abilities on you and letting your team down, leaving you feeling like an over-sized minion.
