Round table

It’s worth a try, but I’m afraid the main feature of the template will disappear.

That’s a strange concern; the original Spider won’t disappear, and those who like it can continue to play on it.

- increase the passages through which the rush occurs when meeting, to 9K.

9k is too little; under certain conditions, it can even be broken through on the first turn, so at least 12 is needed, preferably more, and even better, remove the passages altogether – fewer connections mean fewer one-sided games.

Those who enjoy intense, close-quarters combat have moved to Jeb and Diamond, while those who prefer to grind until the 2nd month remain on HLU, rearranging the GM, etc.

You say it as if it’s a bad thing :D
In reality, with the current pace, strong players don’t often reach the 2nd month. This argument reminded me of the debates on HP, when comparing MM6 and CM. Critics of MM6 also claimed that on HLU+, you would have to run around for months.
And in general, if you understand the request and are going to respond specifically to the request, then why leave short passages and practically force “intense, close-quarters combat” on those who, in your opinion, don’t want it? There is a risk that the result will be the same as with the original Spider – just another decent, but not very popular template.

- increase the size of the treasure rooms.

Maybe that will be enough, but I still have the feeling that on Spider, even larger treasure rooms are more often empty than on other templates. I may be wrong, but it seems like something is wrong with the contents.
