I understand that a lot of this was rhetorical but I'm gonna try to address some of it seriously so you can learn from this.
So apparently, people got mad at me not optimizing an alpha staged map. Sure whatever, but then people complained about the file size saying I can't properly pack. Oh well I am sorry that I can't pack a Frontline themed map with assets that take up that much file space, there is nothing I know I can do to combat it and rather than complain please just tell me what I need to do.
Repack your map, this alpha is a larger filesize than shoreleave. Nobody wants to spend 5 minutes downloading an alpha map, save the frontline assets for a later version.
You should be aiming to make a good layout first instead of letting the detail limit you, and only use minor gameplay/placeholder props when you absolutely need to.
And then to complain about taking damage from barbed wires (which is supposed to damage you?!) when I pushed it out far enough for anyone to not walk into it when not paying attention. And also why are people complaining about a mine field killing you when it is it's whole purpose to do that! Nobody complained about it on Crashes map, why is it now so bad? The mines are located in one single area on the map and are hard to miss, my bad that you are too dumb not to notice them for a third f*cking time.
These were arguably bad ideas on Shoreleave too. TF2 has gone a long time without having parts of the map deal damage to you outside of large, obviously telegraphed instakills such as trains and sawblades, for a reason. Small props that deal tick damage are awkward and intrusive to player vs player combat.
Additionally, the minefield on Shoreleave is out of the way in a dead-end and function like a deathpit to push people in, not a hazard to traverse, which may be why it was complained about less.
And regarding the comments about my map being a flat uninteresting field with too many props, oh please just when is a map not flat?
Most of the time, TF2 traditionally focuses on using verticality in interesting ways.
Is Barnblitz not just a flat map with a few buildings?
No.
Come on the props are necessary to block sniperlines, that's not lazy that's how it is supposed to be or would you rather get shot at from across the map?
No its not "how it is supposed to be", most maps deal with sightlines by making sure the layout doesnt create them. Props are a bandaid fix, and should not be relied on.
The theme is clearly a war torn city, having rubble and debris scattered around is supposed to immerse you that you are apart of the battle that is taking place. Or did Berlin have clean streets when it got obliterated by the Russians in 1945?
Your theme should not be limiting your gameplay design in alpha. Focus on making a good layout before putting thematic stuff in.
I apologise for our feedback being too harsh, but I feel you have been approaching this from the wrong place, and making excuses for criticisms rather than considering them isn't a good way to get better.
