That was 4 shots of 1 shot each since you were complaining what a single round did, normally of course you fire more than 1 shot. I cannot be bothered to test further yes next time might get 4 kills & 2 immobile results. Its still not the devastating weapon you are making it out to be after all thats 4 shots now I will take 4 with a modern MBT for 3 kills. Possibly try adjusting the Pen level to 40 or so for even less effect vs units on outer circle if you think its to effective.
Banning though changes the entire nature of the battle in my opinon as if CM arty is possible it changes tactics by causing dispersal both in attack & deffence making doing both far more difficult. After all its useless if it misses so if you think your force is spotted dont do the obvious, bit trickier vs planes mind & a general "rule" anyway.
You have to judge when its safe to group up or worth the risk & if he guessed right what your up to it hurts. With CM arty only I end up plotting far more than firing as decide target is not worthwhile as have been second guessed.
When we played you restricted it to onboard only no reloads something like 50 CM rounds only, this made it easy as know what you have once fired. So use tactics to combat & once it fires I know elsewhere I can bunch up for a turn hence you only hit one or 2 tanks a game. My CM then fired taking out most of your CM regulary letting me operate normally while you had the threat of my remaining shells hanging over your force.
Hardly ever use it on armour unless dug in or offer up a target thats just to good to ignore as hitting fast targets as in vehicles is tricky vs a human, a mortar will prep an armored force & its escort for attack nearly as well. But the mortar will not do the job effectivly on targets like SAMS Arty or that ATGM that is stalling the attack.
Not being able to deal with these fast leaves your armour air vulnerable to attack & hence loses.
