My 14 year old cousin speed runs A Link to the Past for a couple hours every day after he comes home from middle school. So what you're hinting at is that he's a fucking idiot for doing so because Skyward Sword is much better because it is more complex, longer, newer and looks better correct? In a Link to the Past the hardest bosses (imo) are Mothula, Ganon and Kholdstare, the others are fairly easy, basically that means it is a simple and/or (suggested) bad game by your standards.
The point of this allegory (which is true) is to say it doesn't matter if people who never played Vanilla on retail are "crying" about legacy servers. Everyone should be allowed to experience this, it is a colossus of modern day gaming and should be preserved as such, regardless of the amount of players and/or money they get from it, though I am almost 100% certain would be enough to cover the cost for a multi-billion dollar company.
Have you taken a look at the upcoming Legion talents, abilities, etc and what the players' action bars look like? It's basically as simplified as Vanilla used to be except you can no longer down rank like you used to (ergo, if you used 3 buttons in vanilla as you said, you were not a good player regardless), they've been cutting down on that for like 4 expansions now.
As said in my previous post - people need to stop pushing their views on others. People like different things. People want different things. Your opinion is your own, you have zero right to assume you know who wants what and why they want it and even if you did know it is still none of your business to shit on them.
