Hey there.
Well I think that people blame balance instead of design when it comes to ISU-152 and Elefants over performing.
The way I see it it's not the range, nor the AI power of the ISU-152 nor the armour values of both units that cause issues. It's design. It's just that the maps for 1v1 and 2v2 are way too small with the exception of Rails & Metal for such beasts.
Yes coh2 has some fundamental design flaws much like opposing front had them, but the suggested solution is to reduce the problem as much as possible.
As for maps we have very few 2v2 maps available and most of them are really 1v1 maps. Sad situation.
Nerfing the range to 80, the same as a panther (I think, not sure) is a bit unfair for such slow unresponsive tank destroyers and would throw them into abandon again. What's the point in fielding them instead of panthers or SU-85s. Ele & Isu used to be a waste of fuel, now they are finally good.
Panther and SU85 have 60 range. Both ISU/ele will still be good with 80 range, its just not so many people will get them because they wont be as easy. They will be specialty units.
Moreover an ISU-152 and Elefant with 80 range would lose any advantage over other tanks in huge 3v3/4v4 maps where flanking is commonplace, and rewarding. Reducing the armour of the ISU is unfair if taking into consideration the elefant's armour, something that bugs me seeing that the ISU-152 is based on the IS-2 chassis it, should be as durable. So the front armour is fine as it stands.
Nerfing range is just band aid patching, they would become useless in 3v3 and 4v4 where the huge maps really trump the overperformance of both. Artillery must become viable to counter them, it is the logical and intuitive counter for a strong defensive position. So is reworking the commanders Mechanized Support (SU) and Jaeger Armour (OT) as both have bombing strikes and heavy tank destroyers that instagib artillery positions. But maybe that's asking too much and expecting too much from relic.
Balancing for 3v3 and 4v4 is next to impossible and yes those commanders have the ability to destory their counter howitzer/pak43 which is ridiculous.
Also, I have successfully insta killed Elefants with the IL-2 Precision bombing strike if 3 bombs connect the TD, that's a semi reliable hard counter right there.
Something I wonder is why Relic does not apply different balance values for 1v1 and 2v2, such as Ele/Isu have 80-85 (respectively) range and then appropriate ones for 3v3 and 4v4, such as Ele/Isu keeping the 100 range? That looks like a fair solution to me.
Lastly Relic won't patch this until Western fronts is out. Anyways The new factions will change the ISU/Ele meta.
Cheers.
The game would become so hard to learn and play in different tiers.
