The season opening scene makes no sense now
The season opening scene had the Alexandria "team" with shields, using spears, bows and arrows and were using formations, showing they developed a working strategy against the dead.
This was for some reason thrown out instantly and they are once again killing walkers by just standing around with a knife in their hands while walkers keep on coming towards them. It especially makes no sense seeing the Whispers use knifes and need to get close, you would think that seeing how Jesus died this way, they would keep their distance from any walker from now on.
