What is the KV-2 good for? I feel like ISU-152 is better in almost every way. I don't understand how to use this tank. Please help me.
Just my two cents:
Are you familiar with StarCraft? The KV-2 is basically the CoH2 version of the Siege Tank from that game (gets a big refire rate and range increase with a toggled ability that sacrifices mobility). In my experience, it actually works best as mobile heavy artillery
. But to use it at its full potential, you MUST use its deployed "turret mode". It has roughly the destructive power of the B-4 (thanks to much higher fire rate) but is way more accurate and will auto-attack any targets in range like a mortar. Thanks to its impressive range when in turret mode, it is particularly effective at helping to deny capture over multiple sectors if you position it well.
Is it strictly better than the ISU-152? I will never say that, but you have to look at costs and trade offs too. For starters, the ISU-152 is more expensive in every way (MP,Fuel,pop). You also have to account for the other Commander abilities that are included with these vehicles. Ultimately, it depends on what you are looking for. If you just want a better TD, the ISU-152 is the obvious choice. But if you want some heavy indirect fire support with more consistent fire rate, the KV-2 is the better of the two for that. Either way, the weaknesses of either can be supplemented by other units in your arsenal.
Functionally, the KV-2 does exactly what it was always suppose to (it was built to be a bunker buster). If you want to talk "balance" maybe adjust unit cost as needed (I don't have any strong opinion about that), but that should be it.
Of course, some opinions here may differ, but from what I can tell, I don't think most people use it as it was intended; if you treat it like heavy artillery, it does great.
