Well, to start off, I would just like to say that I think the 2.10 patch is awesome. I have been away from AHII for about a year now and just signed up for another subscription 2 days ago.
One year ago in AHII (I'm not going to recite the specific patch by any means), Flaks were able to make use of the "No Tracers" option when using their cannon. I upped a Flak Panzer and started firing my cannon rounds from the turret and I could see my tracers. A year ago, I could not. I checked my options to see if my No Tracers option was checked, and it was. I then shot from my MG Pintle Gun and noticed that there weren't any tracers on the gun.
I also noticed this same occurrence when I upped a Yak and shot out of my 37mm cannon. I saw tracers, but none when using the Machine Guns.
Is this a bug? Or a more "realistic" side of AHII that was implemented in the last year?
