It feels so frustrating to play against isu. The isu forces the axis player to get a jagdtiger or an elefant every game to be able to deal with it. Thats effective but so lame to play like that every single 2v2. flanking an isu is a wasted effort it is sitting behind a wall of mines. meeting a mine means pretty much you are screwed for you tanks. do not tell me to defuse mines while beeing under isu fire. and do not get me started about mark vehicle on an isu doctrine you can fuck up pretty much every tank with a few shots.
It is even more frustrating to fight against JT who outrange all allied tds/armour, and has the ability to shoot through cover for lols.
It goes both ways, but honestly bringing down an ISU with panthers are quite easy, especially after the frontal armour buff. Slow ISU cannot handle the power of the mighty blitz!
