Zephyrs. Are not. Anti structure.
Over. 150. Fucking. Zephyrs.
And why on Earth do they have a beacon, which could hardly be used against moving targets, if you must fill half of the map with them to destroy any structures? I guess they are only useful against masses of standing tanks - provided there is a hole in the center of the group where you can place the beacon.
Also, most, if not all Zephyrs could make two shots to the beacon before it disappears.
That's what's the cryo field is for, slowing opposing tanks down so the Zephyr Beacon can be used for maximum damage
