I can try it now, npDepends on the extent to which it becomes prominent. People have been using features of certain ages to win at 150 attrition pretty much as long as 150 attrition has existed - I remember someone on live forums posting a 150+ attrition fight win in the first couple weeks. But we're talking about slow manual battles, also cherry-picked such that you need a lot of sectors to look for the next fight you can win. Not something that everyone and their dog is doing at high frequency.
Among them Rocket Troops vs 8 Ronin can win even if the rocket troops have *0* boost at 150 attrition. The only way to "fix" that is to change the units or remove the 8 heavy fight from the rotation.
In fact, VA artillery against 8 heavy is the only available option. You won't be able to do this trick with artillery against heavy Jupiter. But all this is pampering. Such an attack is built for different. To close the day in GB with ~100 attrition for example. But if I could take part in one or two races earlier , now I can only slowly and sadly pick at the coastal province, a few fights
