I think if it would be only for the trailer then it would look “better”. Like I don’t know how bright a Leo 2s brake light is but I think it would illuminate the surroundings a bit more.
Probably for gameplay reasons they toned it down so you don’t light up the whole forest when you brake in a night battle lol
We both know you and I have different perspectives on what’s good for the British tree. I for one am very happy with the recent Commonwealth MBTs. (and hope to see plenty more, Falcon when!)
