Trying to stop the "Sated Devourer OP, Rito delete NOOOW" threads from appearing
The balance team was not stupid. Yes, the item is overtuned. But these guys did not just go "herp derp, here's an instawin item, gl guuuuyzzzzz ^.^". No, they got an item together with loads of balance levers and sent it in after initial testing (I hope, idk PBE stuff but I assume some kind of testing took place) to see how much it rocked the boat and how much it would need to be nerfed or the champions strong with it maybe needing nerfs.
Balance Levers: Attack Speed Magic Damage on-hit On-Hit effects every "Y" amount of attacks The stacks required to get item to said "op status" The amount of stacks given per Z unit killed (epics give 5, players give 1, scuttles give 2) Status of using On-Hit instead of On-Attack or On-First-Hit-Per-Target (or some other shenanigans)
So on, so forth. Since the item is strong (no one will deny it), it may need to be lightly nerfed in one of these areas. Maybe take 5% attack speed, maybe make the double strike every third attack instead of second, or maybe just up the stacks required by 10? It's possible people. This item is not game breaking enough to be immediately deleted, especially with the time I assume it took them to "create" said item. My 2 cents.
