in my opinion the wide ranging 1N rebid is one of the worst conventions i've ever come across.

12-17 or 15-18/19?
12-17 I am willing to agree, that in a weak nt context, this is not really useful.
15-18/19 I am disagreeing, you dont give up much, the follow up structure is not much more complex
than simple check back / NMF, and you free up a 2NT rebid to show some hand types that are hard to
show otherwise. It also protects light responses, since responder does not have to fear the 2NT rebid
by opener, if he responds with only 4+ HCP.

With kind regards

Why?

because especially at MP which I usually play (although I don't play weak nt) I think it's solving a very minor problem to create a much bigger one. For example let's say it goes 1d - 1h - 1n uncontested. the 1n showing 15-18 what is responder meant to do with a random 8 count? with a 15-17 easy enough to pass at MP, but here partner could have 18 so can't really pass. Likewise you are opener, partner invites and you have 16 - do you accept, it's lower end of the range after all?

Ah right, you were referring to 15-18 with not necessarily five hearts. Yes that doesn't sound too great.

Yes you invite with 8.

If you have 5, you play 1N rather than 2N opposite 18.

No you don't accept with 16 unless you really like it.

There are response structures, that can help you, and eliminate the guess work for one side, because it is clear, who is captain,
the risk being that you end up in a thin 2NT contract, ... but this can happen anyway, if you need to make a jump rebid to show the
higher strength.
With 8 (even with reasonable 7) you will invite, but I play (+14)/15-(-19).
