This is going to be my last post regarding this topic. This is getting no where, and is rather silly. I do understand what you're saying. You want the Roc's Feather in the game, where Link can jump higher and do jump attacks. But the thing is, ledge jumping and jump attacking is just fine. It requires the same things as Roc's Feather jumping except it's only available when necessary. You are beginning to cherry pick and quote mine my arguments to take things out of context (I don't appreciate that); I was referring to ledge jumping being no different to Roc's Feather jumping in terms of timing, distance judging, etc. I was not talking about how it would be implemented into Zelda U or any other future 3D installment.
The reveal and game awards gameplay footage both indicate that Link can bolt off the horse, going high into the air and aim his bow at enemies. This possibly confirms that the Roc's Feather won't make it into this installment due to its redundancy at this point and it would take away the main combat focus of Epona - the "gimmick" of the game, it seems since it takes full use of the Gamepad's gyroscope. Nintendo has not shown interest in having the Roc's Feather in a 3D environment (nor any recent 2D-like environments) and I can see why. And with the sailcloth, I'm sure the Roc's items won't appear in this game. And sure, you won't be able to jump or glide whenever you want, but you will be able to when it's necessary, so I don't think it takes away anything.
This isn't objective. This is all up in the air and subject for discussion, and one I'm going to stay away from after this post. Nothing about this is objective because none of this is confirmed nor proven. I don't see what you mean there. Also this is totally about preference; you prefer the Roc's Feather over the Hookshot. You prefer jumping on a whim over jumping when necessary (ledge jumping) and you somehow prefer the opportunities Roc's Feather jumping provides when in reality ledge jumping provides the same, maybe almost, but I'm sure it provides all the same.
And to put things straight: I respect that you prefer the Roc's Feather over the Hookshot. I respect your wishes regarding the Roc's Feather (or Cape) appearing in Zelda U or a future 3D installment. With the sailcloth and the bolting off the horse move, I think the Roc's Items will be redundant here. And I just don't see anything wrong with the hookshot, ledge jumping and the like, I think they're fine enough and you're not giving them enough credit and go as far as to belittle them (by leaving out or forgetting important information) and blow up the Roc's items. That is how I feel this conversation is and speaking of which, this conversation will just spiral out of control if we continue this trivial topic, so I'll eject myself from it. Thank you for your patience, and have a Merry Christmas.
