This suggestion will get ignored like all the others probably, but eh
Many sieges have been extremely painful lately, especially for attackers, they aint got nuthin, defenders usually spam their soul out on the attackers with cannons, and the attackers only counter are slow artillerys or truck with artillery or tank, which can easily be sunk or damaged by cannons, + the fact theres water fucking everywhere blocking your movement, and holes caused by cannons, actual pain in the ass.
PLEASE for love of the god make fighter planes break walls again, but not fucking melt them on one hit, and let land movecraft move through water puddles, there surely must be some way from stopping them from going through seas and oceans
-make them get blocked by sea grass and kelp
-how many blocks of the craft can be in water
-or something else
