Panther spam? nobody gets a panther these days. when it comes to dealing with medium stock armour the p4 with bulletins is a way better option. when it comes to dealing with the high dps but frail allied TD's the puma or the jp4 is the better option. only when dealing with the is2 or other achieves you may find use for it.
Word of advise:
