the RTS element of realms is definitely frustrating, to the point that I feel it needs rebalancing.
It should not be possible for players to sink half an hour into micromanaging their run, only for a shielded enemy vine tower to decide to lock off the path to the objective for the rest of the map and render it entirely unwinnable. It should be possible to damage the impediments it creates, or cause the terrain to return to normal once it's gone, or for the AI to avoid locking out the last tile required to get to the location.
