So I figured out the main problem with the leg meta. Zombies no longer become a threat. When you kill zombies, the downside is that more can come. When you leg chop, the only downside is that you can't do it often (and even then that's not much of a downside). I think Crawlers should be buffed inorder to make them a constant threat. The dead are relentless, loosing limbs should not stop them from being dangerous.
-
Crawlers should not be able to actually hit you, instead they pull you into a grapple animation without a telegraph.
-
Runners that are turned into Crawlers should crawl really fast, similar to the fast zombie from Half life 2 when it lost it's legs.
-
Walkers should be able to walk over crawlers (Apparently Crawlers bodyblock zombies, if this is the case then it needs to change)
