There's many maps within R2DA that need to be reworked, I'd like to talk about said maps in this post based on objective points torwards them that make them unfun to play or just too diffcult due to certain things, or just obnoxious.
Blox Harbour Campaign - This map is impossible unless you have many coordinated high ranks, the Island is a death ground where you either die before you get the axe, or you die when you get on the raft, the raft moves wayyy tooo slowly with no seats, you just die to either edgars or the bee zombie swarms before you can even escape. I'd suggest completely overhauling the second island to be just as big as the island you spawn on with like a volcano on it or something, with an easier objective like calling in a helicopter or something.
Suburbs - This map is a showcase, not made for gameplay, I find myself being unable to see anything forced to use my flashlight or turn up my gamma on my computer, 70% of the map is covered by houses, the problem isn't the attention to detail but the amount of uncessary game objects blocking your path, and the zombies path, the sleigh is overpowered on this map simply due to the amount of houses you can put between you, and the zombies. There's also a campable cave but that's alright since most maps have campable areas anways. The map also splits up survivors heavily due to the amount of objects within the space, causing edgar death to be expontentially more of a problem.
Coastline Clash Campaign - Another showcase map, this map has too many objectives that are too diffcult, the cart is also functionally buggy ontop of all this, first off, people can spawn vehicles that fling the cart, or can place the tripod mount which can make you stuck on it until the cart is all the way up the hill, the map is also slanted beyond belief, even in areas where it should be flat it's slanted, it should be made much flatter in some areas. The other thing that needs to be removed is replacing the light bulb, you are defenseless if you try to do this objective, and are essentially punished for existing, because if you drop it, the light bulb is sent back through entire dimesions back to spawn. It should only break if it's dropped off a cliff or zombies hit it, the boat should also come into the spawnpoint, not orbit the island then go to some random area where it'd be stupid to even park a boat at, grow a brain boat drivers smh. Also the timer for the boat leaving shouldn't be ~40 seconds, but ~20 seconds if the previous change isn't implemented because it takes a minute anyways for the boat to even get there, by that time your already at the area, and the boat isn't even there.
District lll - This map is good, other then the boat, the boat is the ultimate camping area, if you don't have a brute who can press the E key on their keyboard, you've lost the round as a zombie, and it essentiallly becomes a 24/7 foxriver grind server on repeat for 8 minutes until the round ends, or a brute gains half a brain to destroy the structures blocking zombies from entering the area. A way to fix this is to just make a seperate way onto the boat, that way it's a two way fight instead of a one-way like most other common camping spots. Maybe a christmas tree island where you can pick up gifts during the holiday for items that also acts as a second way onto the boat.
Honorable Mentions -
Subway Campaign - The objective is ok, but the swarmer can hit you when you sit on the subway train through the wall, and can kill you. It's more of a problem with the swarmer hence why it's in honorable mentions.
Mogadishu Transit - The killbricks need to be reworked, as some of them are too close to the actual map, they need to be replaced with stun bricks that just make you fall down the hill.
Victoria Harbour - The same as above, these walls are worse because you can't defib when dying to the kill walls on this map either. Stalkers also commonly throw you into the walls like no tomrrow.
S.S Boliviar - This needs more to it, not really sure what, but it just needs to be bigger somehow.
Broken Map Mentions - (Probably known, but going to state here anyways)
Kingstreet Campaign - There's two trucks for some reason ontop of eachother, requiring you to get many wheels to get one of them moving.
Sewers - This map breaks servers when it's voted, it never loads, I can't really talk about it other then that.
That's all I may have missed some stuff but that's all I had to say, it'd be cool if these changes were made, as some of this stuff is just general annoyances or obnoxious things about maps.
