Adding on this, some people also just give improvement suggestions in the chat or after batling the team. So people don't want to retype their suggestions again.
Also, some teams just don't have much in terms of detail, meaning that all we can do to improve the team is give the standard movesets in place of whatever strange things people new to the game decide is a good idea. This gets boring after multiple answers, so we tend to stop answering except every now and then (similar to how some of the higher ranked users such as myself operate in terms of answering questions on the Pokebase).
