Why would you even want a second one?
It's a luxury sure, but getting to it in a normal game on average is very difficult. I see this defense of bad things a lot; because they said bad thing is good in some games rarely this means that despite it under preforming on average it's fine. If T4 is going to be the super - expensive tier then the Units in it need to be just a little bit cheaper/better.
Iv done my best to try and use the Sturmpanzer IV lately but it's horrible pathing just makes it plain useless. I spend half the time it's alive just fucking around with it trying to get it to go were I want I shoot were I want.
Never build the Sturmpanzer IV or werfer. Both are too UP now. The Sturmpanzer cost 165 fule while t3485 cost 130 fuel and E8 cost 140 in the new patch. Just LOL...... Just never build them.
