Totally agree with Sheikyerbouti.
I think my favorite map is a map that doesn't exist, Almost like a point of intersection if you extend a line from.... say, Operation Cobra, Point du Hoc, Purple Heart lane, Fall of Tobruk & St. Vith.
I like Operation Cobra's combined arms best - Its late war, tanks are powerful, but never OP, tank destroyers can enjoy the use of the terrain, airplanes come in interceptors and ground attack and you can enjoy the game simply as a pilot,
HOWEVER, the objectives are far apart and part of the terrain, in spite of Natty's stellar work to improve this, is too damn open, specifically for infantry, but this is WAy better than it used to be.
Also, I LOVE 88 positions... can't explain it.
And late-war American weapons, especially the M1 garand beat any Lee Einfield in gameplay fun, IMO. And the asymmetry between that and the accuracy of the k98 Mauser is perfect.
I like Point du Hoc's perfect objective layout - its clear where to go and where the enemy is. Back-capping is possible, but it takes a lousy attacker to allow the enemy to slip through. The defenses are epic like the ack-ack and mg positions, nevermind the mortar, and the attack on the cliffs is challenging as it should.
I like Purple Heart lane's bocage fighting and for some reason, squad play is used to its fullest in this map, even more so than PDH, which has it too. I like those confused fighting between the bocage and the artillery raining down. I do wish it had more brush in the open areas than it does, it forces the gameplay to move along the margins.
I like Fall of Tobruk's moderately open city - Where as Mersa Matru is way too open making both tanks and infantry very vulnerable, except at the south, Brest becomes a frag-fest at times. I love both of those, but I think Fall of Tobruk is the ultimate CQB map with tank support - Fuck that, it's the ultimate CQB map, period.
I like St. Vith's tank support, mobile AT guns and the sheer number of flags - It divides the city into choke points and allows each side to hold a side, making it the ultimate battle of attrition, street map. Like how an imaginary Anheim could be. And it has the very different terrain type, although I much prefer bocage and city than snow desert and city.
Now somewhere in there, is my perfect map.
A massive 64 or 128 sized French city like Caen or something with a cathedral at the far end of the road, the final base, and a wide dual carriage road right up the middle heavily guarded by 88s or PAK guns that are speckled across making it impossible to drive straight through unless you secure the side pockets.
To its side are side roads that allow SOME tank access and a infantry CQB through houses but with so many blown out buildings that are a sniper/ lafette mg's delight - And there are mix of static mgs and deployables, and oodles of German sniper kits, passages through celllars and sewers as well as the ability to blow down certain walls and tank traps to clear a path for infantry, tank or both.
One one side, the Germans, with some tank and tank destroyers, lying in wait at various parts of the city, never united in any armored force, but positioned to ambush.
On the other side, the attackers, the US (I said, LIKE Caen; NOT Caen itself); their armor column coiled like a spring, air assets able to do some bombing in the more open areas, but limited by ack-ack and 88s to dogfighting and removing enemy static positions.
...But before they can attack the town, they MUST pass through the bocage surrounding it.
