Haha, wow, you do realize you can say the same thing about OOT right? Hyrule field is the epitome of excessive in that game, it was one huge field with NOTHING to do in it. More to discover in OOT? I think you need to play OOT again because TP beats it over the head when it comes to discovery.
Epona, one of the main complaints about OOT was the empty field (I'm sorry but your "holes to fall into" was not discovery, and most did not care for it. So I think Nintendo found a balance between utilizing Epona and not having to trek accross a long distance. In fact it could be argued that the warp system was far more Zelda like than OOT since the whistles did that in LTTP and LoZ. Heck you could even argue that Epona is anti-Zelda if you want to start saying what is or is not Zelda. So please, this is bordering on silly hate-rage, the complaints about Zelda: TP were always about it being too similar to OOT not some mutant like Kairon is trying to suggest.
Zelda: TP was the next step in the Zelda series evolution, like Wind Waker, it integrated more cinematic elements into the main story. Because of lack of N64 hardware limitations they were able to expand the world leaving more to be explored. More than once I was in awe of Zelda: TPs world, and I could not wait to explore every nook and cranny of it. I have no doubt Miyamoto would have expanded the Zelda world himself if he had the hardware power to do it, in fact he was a key part to TP which I think Kairon is forgetting. To even argue that OOT Hyrule field had more merit than TP is ludicrus at best since it was TRUE filler, regardless if it had secret holes to fall into. In TP I hated to go past areas in Hyrule field that I could explore, in OOT I couldn't get through the field fast enough.
