In this case, it is only DECA’s opinion that matters.
I am personally against the permacloaking script (even though you do have a short period without your cloak thanks to the cooldown), simply because it takes out what I see to be a major part of this game: human skill and error. As you say, a skilled rusher can time these ability uses almost perfectly, but why use skill when you have this script? A non-permacloak script user must time their ability uses in their head, adding to the complexity of a rush and bringing in a little extra required skill to the rogue. All the user of this script must do is press a key, negating any difficulty in using a character that is left after pets.
Scripts that let you spam messages are fine, as they don’t take away from the skill required to play this game. Scripts that make the game easier by taking out the need for skill aren’t.
This is the game’s way of telling you that you have been playing too long. Go get some fresh air.
