My favourite map so far is Studienka.
I can't give my opinion about the balance in the new maps (not enough time played)
However, I can give my opinion about unbalancing stuff/points in the old maps, and since TS4ever said the next patch could be for other maps too (if I am not mistaken), my suggestions for 64p maps are:
-Supercharge: Increase the flag capture at Sidi Abd el Rahman. Too many effort to take it,
and half of the map is not playable because of this (the brits rarely reach the 2 final flags).
-Alam Halfa: Bring back the Valentine tank please. Originally there were 1 in the final british flags, but if possible add 1 more in the first 2 flags. Besides, Valentines were common in N. Africa as you sure know (it wouldn't affect the balance IMHO: Stukas, LeFH 18, Pz. IV F2 can easily kill them).
-Siege of Tobruk: Reduce the points (from 900 now to ¿700 or so?), because is a matter of time that germans win the map 90% of the times. Also, ¿more cover to the 25 pdr maybe?
-Mareth: Add 1 Semovente 75/18 (and replace a Marder III). Not because of the balance, but because the 75/18 is awesome
.
-Lebisey: Seriously, this map needs more points. The map ends after 15 minutes, I don't know how many points it has (400?), it's clearly insufficient.
-Omaha Beach: In 2.52 it had a lot of points. It made sense because it was hard for the yanks to conquer the beach, now in 2.53 it makes no sense anymore. The players know how to play it.
-Op. Cobra: The spawnable Panzerfaust has balanced the map for the germans a bit, which it was neccesary. But if possible, add at 1 more AA system for the germans (static or mobile).
-St. Lo: Increase the points a bit (no more than 200), so the yanks have more time in taking the Hill.
-Villers: Currently 900 points, which makes it one of the most long maps in FH2. 700 points or a bit less would be perfect.
-Pegasus: Too many points too. Easy win for the germans most of the rounds.
-Hurtgen: Ditto but for the yanks, and also I would reduce the cap. areas (the south flag is very easy to capture for example).
-Bastogne: It needs a bit more points. Too hard for an average USA team defending 3 flags at a time.
-St. Vith: Maybe it goes against the historical accuracy but, can the yanks have artillery and a couple mortars?. The germans win most of the times.
-Sammatus: Is possible that the soviet mortar is bugged?
-Seelow 32p: Adding a 82 mm soviet mortar.
All of these unbalancing issues is what I feel they need to be changed, in my experience playing online.
