what he says is true
if you just walking circles and shoot them with thundergun it can be done very easily but it's boring
Those crawlers can sneak up on you, so you kinda need to be on edge. But nobody said anything about getting to high level being fun. It never was. Grinding on levels 100+ on W@W was just a borefest. My friends when we play on xbox usually get to <25 but its always real fun.
