To be fair, people who didn't play the beta just find it easier to jump on the bandwagon and say EoC is rubbish. I always felt it was just released far too soon and thus the damage was done. They should have introduced all these changes more slowly. The action bar could have been released and just helped us train skills faster. Then they could have released dual weaponry and get us used to that shit. Finally, release SOME abilities and gradually have more and more. But they just said, here, take what you get. It confused me, it confused others and most people (even the fans) agree lots of it wasn't ready or could have been improved more. Granted not many people were playing the beta, but that still shouldn't have prevented them releasing the update in parts.
No, I tell you what really killed RS. You guys. ANYONE that botted has killed RS. People got greedy. People wanted skills as fast as possible and just forgot to enjoy the fucking game. The economy just got fucked up and people started buying their way to skills more and more (i.e. buying gold and then using that gold). Because people started doing this, genuine players could not compete so they either quit or started botting too. How many people can actually say they have never botted in their lives? Bullshit that the best part of the game is experienced at higher levels. That is bullshit. I love questing. I love training my skills and getting those levels and getting up the highscores. But its no longer fun when some fucker just bots and puts zero effort. So no, EoC didn't ruin the game, but the greedy botters and Jagex for not doing enough to stop them.
