Haha you obviously don't seem to understand what people are saying... The problem is that it has super AT and AI: its AI is good enough to wipe infantry from 70 range but still hardcounter every tank except Ele/JT.
What would you say if the Ele/JT had similar AI capabilities? JT already is more expensive and less mobile, and Ele cost roughly the same but
Which is what I thought at first aswell. But it seems that most people would still have a problem if the AT was removed, the AT isn't godlike. If the AI ability remained the same but the AT as removed, would there still be an issue with this unit?
Reading between the lines of posts in this and other threads on coh2.org aswell as replies on the official forums it seems people would still not like the squadwiping potential of the ISU even if the AT was removed. You can still cover it with SU-85s, Zis guns and if teamgames, Jacksons.
