Too many maps with exploits and weaknesses
There's a point right now where it feels like every other game on larger maps and maps just isn't much fun because of illicit roof access, very wide fields of fire into the enemy HQ zones and first objectives being tough-as-nails in Breakthtrough.
Roof camping can make Sobek City and Manhattan Bridge pretty obnoxious to play. Liberation Peak and Empire State both have initial objectives where the defending team has way too beneficial permanent cover. I get vibes from Devils' Anvil in BF1 where getting beyond the first sector on Verdun Heights was something of a rarity.
There are multiple maps where one's spawn is incredibly easy for the enemy to camp or just straight snipe into. On Iberian Offensive in Conquest, I've seen how it's possible to bottle up one team from the G objective since that objective can dominate the only two tight bottleneck exists from the HQ. I've also experienced being fired on pretty much directly after spawning in HQ on both Liberation Peak and Empire State. Pretty sure it happens on other maps too, and if I recall, it wasn't just from snipers accessing places they shouldn't be able to get to.
