The ISU, Elefant, and JT have always been terrible units when isolated an unsupported.
The ISU used to be peerless at leaving an Elefant or JT unsupported. Elefant and JT? Not so much. I dunno what there is to debate.
It was a linear and predictable matchup, but it kept people playing because it was at least a bit dynamic. Suppressing ISGs were worse IMO, and the early days of trolling with CAS were probably bar none the cheesiest bit of CoH2's history.
