What are the hardest sectors/maps to defend/attack on?

Like always this is highly affected by the competence of players and which squads are communicating. But in a balanced scenario —where all the high level players don’t just join the same team—what’s your opinion?

I’d say Provence can be really tough to attack on. Defenders have a height advantage with great lines of sight in the 1st and 3rd sector. US tankers love to camp the hill and never flank. I always try to flank right and get in the buildings but most players seem oblivious to this option. -Al Marj is also a contender, rarely see attackers breaking through the first sector, similar to Fjell.

Aerodrome is probably up there for the hardest to defend due to the tank imbalance and the size of the capture zone on the 2nd sector. Panzerstorm can also be really tough, I rarely see the defenders win. At least not in the 1st and 2nd sectors. Same with Arras.

Let me know your thoughts
