turrets can force ppl to use something heavier than lights/ew for roamings, that can increase pvp fun (less but more quality).
btw, there can be some heavy robots with ability to deploy as a turret - slow and unable to fight when in travel mode, but deadly in turret mode. lets call it siege robot for example. moar wayz to use tacticz, less ways to use blobs, if implemented correctly. in stationary mode they can f.e. lock and shoot multiple targets at once - as if it indus/ewar modules, also maybe interference can affect them lesser or they can cause great interference around them, kinda sorta
Have a productive day, Runner
