Oh wow, they really have to be great ;).
I guess you mean sneaky routes for ambushes. I think the number of these remained to same at best over the past few years.
And I want to note that my point about scouting still stands here:
Looking at this route, if a light tank noticed and scouted you, maybe before you killed him or by hearing you through some buildings, your plan would have very likely failed. Depending on how the battle unfolds, your chance of survival is very slim, since in this scenario, where you’re in the middle of the city, surrounded by roads, every enemy knows practically exactly where you’re going.
So the success of these tactics depends massively on whether the right type of tank notices you or not. This is a kind of gamble that is intended to help beginners, but massively limits these types of tactics.
Do they have an explanation for that? How do they think tanks like the Object 120 should be played? By rushing the capture points?
