What is your issue related to? General
Summarize your bug Basically when i use the siege mode on the AAT the vehicle stops (as it is supposed to) but it doesnt fire the actual heavy shot (instead he fires his normal shots...)... Only THE FIRST TIME i played the game during the 10 hour trial it worked properly and then even though i tried to fix the installation of the game (in case there was some issue with the game files BECAUSE ON YOUTUBE OTHER PEOPLE DONT HAVE THE SAME ISSUE WHICH IS VERY STRANGE TO ME...) But still no solution and it is annoying for me

The sige mode of AAT fires the normal shots instead of the veavy ones... it happends 100% of the time for me and i noticed that in other people works fine which is rly strange...

Not only that but since it doesn't activate the top and you still shoot the bottom turrets, you cant even aim. you can only move the cursor up and down. not even left or right.

Same problem here. If I remember correctly, I think it worked a couple of times for me in the beta, but every time I've tried it since the Access trial, it hasn't worked properly.

 Cannot move cannot of ATT using second ability and cannot fire it. I have checked the settings, I have it as my friend, who can work the main cannon fine using mouse. Pressing the second ability and firing it is firing side cannons. I have only changed ability settings to 1, 2, and 3.

PC. I have experienced the same bug. The big cannon of the ATT is not working as expected. The two side cannons are firing and the animation of the cooldown time of the second ability starts. The vehicle cannot be moved which is as expected, but the main big weapon (middle ability) cannot be fired. I have tried this multiple times and wasn't able to get it working on the Kashyyyk map playing as the droids.

PC. Yes this also does happen to me. After entering the AAT I couldn't use the second ability (the middle one). The cannon's head does not move and instead, you shoot only with the two side guns. The animation of the run time of this 'siege mode' does work, and it goes into cooldown correctly. But it doesn't activate anything else then. When pressing the middle ability, you cannot control your vehicle (which is correct) but you can't shoot with the upper cannon.

I tried a few times but it doesn't seem to work.

According to this post, it might have something to do with your key bindings: AAT siege mode bug

Summarize your bug Changing the keybind for the AAT's Siege Mode makes it so the ability cannot be used.

Can you tell us the date (MM/DD/YYYY) that you saw the bug? (08/04/2017) It's been there since beta and is still present.
What time did you see the bug? (HH:MM AM/PM) (12:00 am)
In what game mode did the bug occur? Galactic Assault
What is your time zone? CST - GMT - 6:00
Steps: How can we find the bug ourselves? Change the "upper ability" keybind to something other than the default "E" and attempt to use the Siege Mode ability on the AAT.
What happens when the bug occurs? Changing the keybind for the AAT's Siege Mode makes it so the ability cannot be used. You can still activate the ability with whatever keybind you've changed it to but once you toggle into Siege Mode you cannot pivot or fire the Siege cannon. Instead you are stuck in place and can shoot from the main side mounted blasters. You can only properly use Siege Mode if the keybind is the default "E". This bug doesn't appear to affect any other vehicles.
What do you expect to see? The AAT's Siege Mode ability should be able to be properly activated when pressing the assigned key.

This is a problem for people like me who like to customize their controls.
