Again, that's going to have more to do with you than with the unit itself. The Elefant is enough to dominate all Allied armor, and is very hard to flank when it can see enemies coming from miles away with spotting scopes and when it's properly supported with Pak 40s / Schrecks or other tanks for support to prevent a dive. The ISU-152 does not dominate the meta like the Elefant did and still does.
Also, fun fact, the Elefant is actually better at dealing with flanks because it has better gun traverse than the ISU-152. Top Speed hardly matters there. The Elefant has a faster reload, higher alpha damage (which means two shots and a faust can kill a medium tank or a TD) and doesn't need to switch shells first. The only advantage the ISU-152's got here is slightly higher rear armor, that only helps against Panzer IVs because the Panther, Jagdpanzer IV and Stug ausf.E are guaranteed to penetrate it at any distance.
Go watch the 2v2 Masters Cup here and tell us how many ISU-152s you saw compared to how many Elefants. These matches show how dominant the Elefant was in most games, and how incredibly hard it was for the Allies to take it out.
We have to agree to disagree then. My question is still is the elefant that much better to make it that eaiser to kill than isu? Imo no.
About spotting scope, it just got nerf. So did command tank. 2 further hits to elefant to raise the above questions about why wehr paying more always.
About flanking, imo both their guns are so slow, it wont matter. I always thought rotation is more important to cover your rear, which why Churchill are quietly op even they are slow. I also think faster isu speed allow it to reverse out faster importantly. Besides the percentage different between their 2 plus points still higher for isu.
Wehr have to depend on stug you say. Then soviet have su85. Isnt it better?
About the 2v2, i made comment back when i was viewing. Elefant was keeping wehr in the games. If there is panic puma, we have essential elefant. As i play 2v2, i totally get being locked out by 60TD as the game progress. Back then ukf just dominant with Churchill.
I think there was a match up between isu and elefant in a map with hans/devm vs some other. I don't remember elefant domination.
