I agree with their sentiment that the "CB requires no micro" argument is totally overblown. It saves you a grand total of three clicks and some map awareness while targeting whatever it wants, which might be a lone mortar squad, when a well placed regular barrage in a target rich environment would usually yield better results. And something being micro-less isn't really the best argument against it, because autofire for many units (mortars etc) is equally micro-less.
I would like to replace but, but actually because I think the ability is meh (it won't hit its intended target most of the time), not overpowered or whatever.
Actually, while you are right, you are also a bit wrong. On paper yes, but in practice, at least in 3v3 and 4v4, CB can be used with great results anyway.
Even if a player knows about the existance of LeFH with CB, its still hard to track it down with everthing else happening on the field. Plus on top of that nature or 3v3 and 4v4 maps, will usually allow you to bombard a choke points resulting some damage.
On top of that, you can just leave LeFH for a while on CB just to vet it up quickly and then comeback to in ones it vet 3.
It gives a lot of pressure for your opponent basically without any input from you. Not to mention, that few clicks arent big deal when nothing is happening, while few clicks during fights + precision of them are really helpfull.
