Why return? Elephat is useful unit all the time. All you need is good support.
If ISU can hardly hit anything right now it leaves SU without long range AT. Prepare for IS2 in every game crushed by Elephant.
I dont get these changes. I mean Jadgtiger should be albe to auto-fire but not through obstacles.
Same with ISU, just reduce AoE. Make it more like Brummbar rather than making it useless.
Wether Jagdtiger nor ISU are useless, they require just way more action by the player imo.
