Instead of Nerfing Devourer, change Rageblade
Devourer doesn't see a lot of high-end play, because the stacking mechanism is too taxing at high end so other junglers can dominate someone with devourers. I think a change to Rageblade would be more suitable.
GUINSOO'S RAGEBLADE
(+30) +40 attack damage
+40 ability power
Passive
UNIQUE: Basic attacks (on-attack) grant 2 stacks. At 8 stacks, gain GUINSOO'S RAGE.
A stack grants +8% attack speed, (+3 attack damage) and (+4 ) +20% bonus AD) (() +5 ability power for 5 seconds, stacking up to 8 times, granting a total of +64% attack speed and +40 ability power.
UNIQUE – GUINSOO'S RAGE: Deal (+15%20) 10 ((+7.5%) 10% AP) on-hit magic damage to the target and nearby units in a 350 units radius area of effect.
This change would shift its power slightly, giving it less attack damage and on-hit damage early on (which to me, is the problem with the item). It would scale into the game slightly better and be better for true hybrid builds due to the slight increase in on hit AP ratio.
That way, the pesky devourer-rageblade junglers shouldn't be able to completely dominate low-mid elo so much.
