He is spot on. The game doesn't need a flashy new mechanic. The game doesn't need this new and exciting thing that is going to make the game amazing again. The game needed EXP nerfed in the JG and specific early game Junglers who had too good of clears severely nerfed. With this Scuttle mess it is exactly what Meteos said you are doing. Instead of nerfing and working on what needs to be worked on, you add this Scuttle idea that is not making the game fun and isn't enjoyable to play if you are winning or if you are losing. Why did you not work on what needed to actually be worked on in the first place?
You work on new champions knowing almost your entire roster needs a rework or VGU, but you introduce new champions and waste your efforts on Ryze, Ahri and Lux for half of the year. We don't need a new flashy champion or a new flashy kit for a champion that was in a good spot to begin with, we need work to be done on things that are broken, not living up to expectations, and are blatantly ignored year after year.
No matter what you do it is going to be a double edged sword because you don't actually work on the problem. You implement some stupid new little mechanic that didn't even need to be in the game in the first place, instead of working on EXP and early game junglers.
