Can you tone down the Tesla tanks a little bit? because they are very OP in team game at the moment, especially in late game. My suggestion is -1 range or -1 bounce target or -50% damage against medium armor or 15 bounce damage instead of 30. Or combination of those suggestions.
Also, tank destroyer still feels a bit undesirable to use because paying 900 credits for a tank and I can't even do any damage to a building is just too much. My suggestion is to change the verse for building to 10% instead of 2%. This still makes them not very good against building, but at least they won't be completely helpless against buildings neither.
