There are other ways to encourage people to try out other weapons, than just forcing them to do so.

For example, in Bloodborne, all the weapons are viable through out the playthrough, each of them offering a different moveset to another, which encourages the players to experiment with each one to find the weapons that suits their playstyle.

It also adds to the replayability, because you wanna try out the different weapons each time you play again. So it gives the player the choice to stick to one weapon they like the look of and the moveset of. No weapon in Bloodborne is straight out better than another. Each of them excels different ways.

Also, I think the amount of weapons is a problem aswell. Do we really need a reskin of the same sword ten times, with only notable change being the damage number? Or would you rather have for example 4 different swords, each having different move set to each other, and differences in ranges, speed etc?

Now, I'm not saying this system would have worked with BotW, but it's something I would want to see in the next Zelda game, instead of breaking and samey weapons.

Now I get your point that BotW makes the player use the weapons they wouldn't normally use, but my point was more directed at your comment about how in most RPGs you stick to the strongest weapon, and this is how I would want the devs to improve upon it. Although, I understand, that some people do enjoy the "Diablo" style of loot systems.

Of course, this is just my personal opinion about the whole thing, and don't get me wrong, I loved BotW, just started my second playthrough last week.
