1- Points you get from repairing. You should NOT be getting as many points for repairing as the other team does for hitting the building. (Looks like you get around 80% return.) Should be closer to 50-60%.
2- I'd like to see the beacon notification system revisited. I feel like it's much harder to see and hear when beacons and nukes are placed. Could the notifications not be more static? (Stay on the screen a bit longer.) In the original, when an enemy beacon/nuke was being placed, it clearly overshadowed all other sounds in the game. Now, you get one quick message and a semi-audible notice.
3- Tank angles. If you are at a lower ground level, you can NOT shoot over hills, etc while in tanks. Even if my tank turrent is clearly pointed over the hill, I end up shooting ground in front of the hill. (Most noticeable in art, but that could just be a result of me using arts the most.)
4- Mobius reload issue. If your magazine runs out on the mobius and you don't release the left click, you can waste "ammo." If you keep the button pressed through a reload, the gun will "fire," ammo will be used, but you aren't actually attacking. If you aren't careful, you could waste half of a magazine before you realize you aren't hurting anything.
5- Officer rate of fire. Drop it by 25% if possible. Also drop the magazine size a bit. This should help with all aspects of officer balance.
