Recently I have considered the value of "plates". With a 1.5 boost to an attacking type with no penalty, in theory it appears that they can be quite viable.
For example:
You have a banded azu
The band gives all of your attacks a 1.5 boost, making you quite the powerhouse
Aqua Jet/waterfall (being the main moves being used) will easily ko, let's say, a doryuzu. But what if a ferrothorn switches in? you have to switch, he sets up, etc. it's a big mess in general
But what if it was given a splash plate which would pseudo-band aqua jet and waterfall and then allow for more coverage?
It provides less power in all of your moves, thus giving less coverage, but when you are locked into a choice move, your coverage is far smaller
