With all these changes with the jungle items, it reminds of that teaser trailer that appeared a few months ago with the caption : "Hold on to your buffs".
I thought it was a teaser for the GP rework (which is coming soon said Rito) or the Prehistoric Skins but apparently it has a different meaning warning us for all these changes with Magus/Runeglaive and now Devourer.
I feel that at the next cycle. they will change Warrior next. It seems is that they wanted to give these jungle items some more gimmicks so that other roles, not just the junglers, would benefit from them and since Cinderhulk already has one, I think it's safe to say Warrior will either get changed or be replaced.
What I'm saying is just pure speculation, but it's kinda hard not to think about it with all these changes...
