* Amiibo stopping completely for 10 seconds - 1 minute
It can be a common occurrence with Amiibo, especially when it's Amiibo vs Amiibo. It's just something they do.
If anyone else has these problems please let me know* Amiibo spamming taunts
Define "Spamming taunts".
Lower level Amiibos will of course use taunts; however once they get to the mid 40s to max level (50) they stop using taunts altogether. I have just about every single Smash Amiibo, and never once experienced this issue at all. Never heard of this issue.
* Amiibo (With long range attacks) Using the same move constantly (spamming)
From what I read and understand, the more an attack lands the more an Amiibo will use it. Also some Amiibo are known to be more spammy in nature as well as not use certain attacks at all. If you want them to stop spamming long range attacks don't use them yourself and get aggressive. The Amiibo should fall out of the habit as long as you don't give it the space to use the move.
