People place about 10-15 horde beacons all around Seattle, this makes it very hard to get close to Seattle, let alone raid it, so I think it'd be better to limit the number of horde beacons one can place, so it ends when we destroy only one beacon and not look for the rest that same person placed in a different location. On top of it, the zombies have more health than the usual horde beacon zombies, especially the mega zombie, I kept shooting his head and emptied FOUR matamorez boxes (one box has 36 bullets and each headshot on a zombie is 109 damage) on it and it didn't die, a normal mega has 2500hp and a horde one will have a little more, not +15.7k (144(bullets) x 109(damage per bullet to head)) as the mega did.
So, if you could reduce its health, that'd Be great. Or change the spawn chance of acid zombies to 0, so people don't constantly have to jump around like maniacs due to the acid and expose themselves all the time to shadowstalker snipers.
