I've almost beaten BotW. Cleared my 120th shrine today, you almost have enough to max out things but I choose three full stamina wheels with 27 hearts. Now a single temp heart ingredient is all I need to hit heart cap which is nice since you get full recovery out of it.
Cleared all four dungeons too and mostly just been working on obtaining missing armor and getting it upgraded enough for set bonuses. Weapons are not a problem now, I can mow through a Scout for some quick Guardian Gear and I'm proficient enough with Lynel hunting I almost exclusively carry their bows & shields, and heck I barely use shields since parry timing sucks.
And the game is no where near as good as OoT, or even LbW. Through it's better than Triforce Heroes, at least until Nintendo kicks it in the shins telling it to make more money in a HD remake on the Switch or something. Really the complaints remain the same, the world is too murderous, the map has too many empty spaces, the shrines are to forgetfully repetitive, not enough creature types, weapon durability is annoying, blood moon glitches are terrible, poor coding on cooldowns, forced dragon farming (you need x15 of each dragon assuming no missed shots) sucks, star fragments aren't rare just tedious due to the amount of loading screens you have to deal with, Nintendo is blatantly lying about nerf patches, it turns out you cannot sequence break the game*, etc. There is just so many things.
*Invisible walls prevent you can flying into death mountain even if you find a way to glide over, the bird is animation-only so you can't rocket your self up to it and land, the Camel's feet are explosive-proof until you progress the quest chain enough, Link is coded to randomly kill him self if you get down from the starting area without the paraglider, and so on.
A few things they really need to fix is the introduction of about sixteen new enemy types. Like undead at night can be expanded on with Poes, Gibdos and Redead. Dondongos, Tektites, Moldorms, and Helmasaurs can be added to mountains. Gargoyles, Knights, Darknuts, and some motherfucking Ironknuckles for Hyrule castle and other ruinous areas. And a modified Wallmaster would be cool, but no more borked start-over dungeons. And there is more than enough iconics to fill out the last four through I'm sure Like-Likes would piss some people off and Leevers in Gurado Desert would be infuriating. They could make boomerangs useful, and then add Goriyas so we don't have to farm lizards, and offer an unbreakable one as a dungeon reward too. Actually, all dungeon reward items should be unbreakable instead of this diamond to repair crap, it's harder to repair them than it is to farm vastly superior weapons in multitudes making them totally worthless in the long run. BotW also needs more "fun" in it, like attacking Stasis-locked objects should break weapons and penalize players for playing around.
Kind of a huge one, for years Link gets to explore multiple worlds. LoZ's master quest, LttP's dark world, LA's glitch dungeon (probably doesn't count), OoC's past/present, Age's past/present/future, Season's spring/summer/fall/winter, TP's twilight, LbW's Lorule, TF's DLC area, even WW technically got in on things with Hyrule Castle. Heck, you can just add a filter to the existing map along with the new bad guys, it's not a big thing to create and it'd do wonders for making things feel more Zeldaish. And buried in this new world could be a Hookshot which would be frigging awesome. And speaking of Zelda items, Roc's feather for increased jumping height, Bombchus for the lulz, Scales or Iron Boots or just make the Zora boots useful and allow diving, and a shovel feels like it's missing more than anything else.
I think adding a magic bar and some spells would also be nice, I feel like those have been missing from these "more realistic games" even through you still get enchanted gear and face magical enemies anyway. You can even cycle it into the shrine system (and add another 30 better designed shrines).
tl;dr: BotW is a beta version of a "Zelda" game.
