Come on guys, lay off him. He didn't burn the constitution, or murder the love of your life.
It's fine for someone to be sensitive about their map. Even if people don't show it, they're still typically attached to their map unless they're a pretty experienced mapper. It's obvious 1745 hasn't had a lot of experience with mapping, and that he's pretty attached to his map. Additionally, he's probably from Europe (spaces before punctuation) so he's not going to take this like an 'average' guy. Show some respect, we all represent this community.
To 1745, we like to consider ourselves (or at least from what I've seen over the time I've been here) a decently high quality mapping community, so that means to be accepted you're going to have to meet what we like to see in maps, and if you want to succeed you'll have to surpass it. We give feedback not to make you angry but to help you improve your map. Yelling at us for trying to help you won't get you anywhere (not to say these later posts were helpful).
On to the map, I will say this about your vents:
Even though you have a story behind them, I don't think any of us here have seen an example of vents being used like that in real life, or in almost any situation. It's safe to assume many other people will have this reaction, based on how many of us have had it, so I suggest taking out the vents so players on your map don't feel alienated from the map when they play it, or at least weirded out. It's important to keep immersion in a map, and weird structures just keep reminding people they're playing a game, breaking the immersion.
Continuing off of immersion, that was why ravage commented about rocks going through fences. It's just another inconsistency with reality that will cause people to step back and go "wait, what?"
If there isn't a gametype in place here, you'll need to get one in before the map is tested. You can get the map tested over in the events section, under the correct Gameday thread.
