Well while I disagree with the OP on normal occasions, we had 3 people from our squad have to disconnect during a raid on the airfield because it was overwhelming and endless. It is impossible to loot the barracks without pulling aggro, and unless your squad is fully equipped with M4 SD's, the airfield becomes a deathtrap of 40+ zombies constantly attacking. I was prone, crawling across from the barracks attemping to get into an overwatch position when I had to fire a 1911 at an attacking zombie, after I fired the shot I could see zombies from both ends of the airfield running at me, I would say probably about 20 zombies total. after a brief firefight to see if I could clear myself, another pack would spawn after those were killed and immediately aggro to my position. So in all, NO the zombies arent hard to deal with if they were not infinite and had a delay. But with an infinite respawn and almost instant respawn, you can get yourself into some impossible situations even when well armed. TLDR: Zombie respawn is what is killing the game for people, not the zombies themselves.
