What if the reason we do not have those are as simple as that this feedback did not reach the devs?
I'd honestly be surprised if the devs aren't aware that we want things like a gridded mesh set. Like, we've been vocal about those things since the very start; there's no way that after so many community feedback was implemented that they would have missed that one piece.
There's probably a reason, because it surely isn't that hard to make from a mesh/texture/coding standpoint. Maybe it's because they want to avoid people going "oh now we can have flying birds!!" or maybe it's because then there's the implied expectation that people want these pieces to be climbable and maybe that's not possible with grid pieces. There's a whole bunch of reasons we could imagine but I don't think they wouldn't do it without one.
It's like with the invisible paths. It took them a while to give it to us, even when doing so was super easy to do. But they told us in the livestream that they at first were adverse to it because they weren't sure how people would handle it and whether it would cause confusion. They then said that the player base was far enough along where they felt like they could do it.
So, do they probably have their reasons? Yeah, for sure. Do I think the community would consider all of those valid? No, probably not; but that's irrelevant, because we'd take a lot more shortcuts than they would. Do I think they should communicate more about those reasons like they did with invisible paths? Yeah, that would clear up a lot.
I feel like they stopped to read the forums except the announce thread ages ago. I wish there was a reliable way of suggesting this to the devs, but I dont really think they read the suggestions section anymore.
I don't necessarily think that feeling is entirely wrong. We used to have more CMs, and whilst they were very busy because they worked on multiple titles all at once; there were more so they had more time for that. So it's logical that they can't read
as much as before.
On the other hand, just like I mentioned above, not every suggestion is going to work. Some are too complicated, some are too specific to a small part of the community, etc. Sometimes even phrasing is a killer when you make suggestions, because if you communicate it in a way where you offer a solution that won't work due to constraints you don't know; then it's easier to go "oh yeah that won't work".
I don't think a more dedicated way of giving suggestions is going to change that much really; sometimes we just have to accept that certain things just won't happen.
