Yeah even at 2275 range t80 and range scaling it's not all that accurate. The Range scaling says it was tested at Rookie level, didn't know you could get t80 at rookie. However, maybe values were done with math and not in game values which would explain why the values plotted look like perfect scaling. (EE it cost 166 points for 'hardened') at 9 ap and that range it could fight most super heavies reliably, however at a cost.http://wargame-series.wikia.com/wiki/T-80
It explains the price drop in RD.
Now Range Scaling doesn't take RoF in consideration, However More range will result in more accuracy . Explains that "sweet Spot" in range I observed with some infantry like Mg3 that just shreds infantry. Technically all infantry have a sweet spot range, as probably tanks would. However Tanks will have much lower amounts of rounds fired, and the hit role is more obvious when it happens. You see Battle Rifles seem to be better for damage than AR depending on the hit rolls (at least for line infantry) as they get a decent hit chance at good range while Subbies on the opposite side of spectrum The thing is subbies have less range and less base accuracy. For SF maybe a bit different as the base accuracy is different and this doesn't even look at Carbines. Maybe why I prefered Highlanders 75 as more all around infantry.
Now The thing that's missing from range scaling that will help balance it out a bit more is RoF. However this is the least clear stat in the armoury as far as I can tell. It doesn't even mention the effects of Size difference on hit roles anywhere in game,
Now Lets talk AA, After range scaling. You look at CTH which is the bread and butter I got from this because it factors in ECM. Which also kinda makes it harder on lower accuracy AA. The difference is huge, Not only does Patriot have better chance to Critical hit it's also going to hit more within shorter ranges which is the Max range of other AA pieces.
I frequently noticed Patriot One shotting planes, however I thought I was going bat crazy. Not seeing my spaag or team mates spaag do one damage somewhere along it's flight path.
So The IR AA with huge range (and High Accuracy), is pretty much universally taken or at least one card will help flesh out your ADN. Now the T80 is kinda balanced by having low accuracy and high range, kinda makes sense why croatle is almost always a good choice, and Chaparrals were pretty bad when they were at like 30% accuracy Take a look .
In ALB it was balanced based on Availability more than the really low price of it. While RD the Chap does cost more.
