A this point, the most "Tactical" approach in this mode now is to oil every possible surface to block the enemy route before you begins any fight. It's amazing how it can completely bug and forces enemy to end their turn after using one or two ranged attack. If they're melee with a ranged attack/spell, they just stop the turn right after using their ranged attacks like Knilles just using Mosquito swarm and stopping the movement entirely because there's an oil field in front of him.
