Not really, no.
Yup. The same sword piece with something sticking out the other end.
Are they different types of weapons? Yeah, sure, but the potrayal of the weapon makes it look the same as every other weapon. The only difference is the length of the thing sticking out the other end.
Here’s the thing about opinions.
If you can make a sound argument with it, I can respect it. If not, then yeah, I’ll question your own thoughts. Your argument was that 2015’s weapons were more repetitive than 2016’s, even if only a few Toa rehashed the same piece and used it differently. That’s not exactly a strong point IMO, so yes, I questioned your opinion.
