Fusion is more or less random too, I know there's some sort of obtuse pattern but it's close to impossible to get the perfect ingredients that will inherit the exact min-maxed combo you want. Finding ingredients is still ultimately luck in the end, especially when you can't even tell what you can chain fuse out of the things you have (yes, I know there's calculators for the weapon itself, but the stats are too unpredictable). You know what I meant, it's the same problem.
I would actually really love to see the game played with base 100 weapons only. I think it would have been perfect. Much less grindy, may take some work to find 100s but not nearly as much. And it'd remove a lot of silly bullshit - no more OHKOs, no more +homing Eyetracks, and you'd get to savor a longer match that doesn't bring the angel out in just 4 kills. I really don't see how RNG is supposed to benefit the game - and last I checked, it was pretty dead, never even got a serious competitive scene in the first place.
Not even a month in we discovered homepass for all your fusion needs. Basically you could turn you router into a Nintendo Zone with a name change and you could then Streetpass yourself without buying another 3DS. About a year in we discovered a glitch that would copy mods from one weapon to another for single matches, meaning all you'd have to do is assemble the perfect mods. With all this it's not even hard, it's like breeding Pokemon in gen 6. Anybody could just smash a few weapons together and get something great.
The game was designed around OHKOs. It's both the primary balancing mechanic and we have
plenty of evidence that proves that it was the case. The very best rewards from the checklist are OHKO weapons (they aren't Clubs durr), and Mr. Sakurai tweeted pictures of a OHKO Samurai Blade that, while slightly redundant, would still hold up today.
If Rollers were Magnus Clubs, Eyetracks are Jrs. Just another fad that you'll never see again, being that they have zero shot cancellation (literally) and move slower then most Staves walk. You want OP? Try Geminis. Literally unavoidable with SR&SH+3, nearly undodgable, and don't break instantly like LOLtracks. Still rather tame in the context of KIU.
Quiet, but not dead. Seeing as we never got a dedicated site things got unfocused... Japanese players started playing like *** (where a good portion of the community was), save hacking came along, painful glitches were discovered and subsequently covered up by the community, and SSB3D and Pokemon replaced it as the primary competitive games of the system. Nothing a proper sequel can't fix. :3
