First one was already announced. T1/2/3 will not be changed, only the new Campaign and Black Hole Gear has set bonus on the armorings. Search for a yellow post, you will find it.

Secend one is not a bug, its a feature... If you stop attacking an enemy, your companion will still continues to attack. Just hit strg+2 to send him passiv, he will stop attacking and you will be out of combat
