Sure but there are not even a single monster with this ability IIRC.Or if they can do it as a bonus action a la Mastermind.
Hmm...
I didn't say there aren't exceptions. I'm saying the rule is "don't Help, make your own attack instead".
People expect Help to work like it gave a bonus to your attack, which would have made it a valuable strategy when you can't otherwise hit except on a 20.
But that's simply not the way it works in 5E. The math of advantage is decidedly different than the math of a bonus.
(Each player - and monster - normally gets a d20 to roll against the enemy. There is little point spending your d20 as a second chance for your buddy, when you can simply use it directly yourself.)
