This has happened medium vs medium tank for me also. I don't expect every shot to be an instant kill or hit but again obviously gold ammo is OP. Basically in my tier I see that gold ammo has twice amount penetration as "normal" ammo. Hey its free and bascially you have to live with if you chose to play for free. Again its a HUGE rip-off buying gold ammo, in my opinion. Like I said in my analogy if for something that you "consume" or actually use in a game and pay real-life money to replenish it is stupid. Imagine paying say and extra $10/month for hunter hours or if you are a serious raider that may double to an addition $20/month.
