You see, sated devourer had some balance, in having to farm 30 stacks, which on average took 15 minutes, sacrificing your whole early game as a jungler. But rageblade can be bought after 5-10 minutes of laning phase, and the fact that it'll work like the sated devourer is very concerning, and the item will never be balanced. If this gets released, you'll basically have to buy rageblade and blade of the ruined king, and it'll be gg. I know I sound like a smartass, but I'm just expressing my concerns on the upcoming items.
And yes, I know that PBE is extremely tentative, and that this may not go to live servers. Yet again, I'm really concerned on how the game state is going to be if this gets onto live servers. Cheers!
